This guy is not only a Charleton he's also a sadist.

[@JasonBarnhart]

I was there when this was recorded. The exercise is designed to prove a point and it does a good job of it. There's also a fair bit of instruction surrounding it that focuses on timing, distance and more importantly, situational awareness. The biggest take away of this is that if you are in close with your guard down, you can't stop the attack. It's neuroscience. There simply isn't enough time. Plan for that. Part of what isn't in this clip is an explanation of how an attack like this can come as a surprise. The training knife is visible but a small knife, razor blade between the fingers or some other subtle weapon you don't notice, can come out of nowhere with little or no warning. Fred initiates his strike the way a boxer does, highly practiced to avoid telegraphing. It's the knife equivalent of a sucker punch, fast and fully committed with almost no warning. The best physical defense is keeping your distance and not letting someone get that close without at least putting yourself in a more guarded position while understanding that even if you do guard, you're going to get cut somewhere. You can take these comments or leave them but I've seen him do this demo more than once, and again, I was actually there for this one. I'm not guessing based on watching a KZbin video. Fred is legit. He's got wisdom worth sharing.

[@apablo09]

Did you guys have to keep your hands down when he slashed? Theres no way anyone can stop that. Hes calm, not telegraphing, he starts the movement, you have to react, make a decision, you initiate muscles and most importantly, distance from arms down to neck looks further than when he initiates the slash to the volunteers neck. Theres no way you can block that.

[@JasonBarnhart]

@@apablo09 no one assumed a guard position. Everyone basically started arms down, including Fred. He keeps his shoulder down. Doesn’t raise it or cock his arm for the attack. It’s subtle. He did it over and over with experienced people. No one stopped it. There aren’t a lot of people who can pull off an attack like that. It’s a skill he’s developed. The bigger lesson is about awareness, keeping safe distance, paying attention to peoples hands, etc. As a former security professional and first responder it was a good it was a hood exercise. Anyone could learn that attack if they were motivated to do it. Fred is tall but not unnaturally so. It would be a difficult wound and probably enough to open you up to more of them. Thankfully most get loud, act suspicious or outright threaten before they attempt something. This was a singular experience. A valuable one for anyone but especially for people engaged in keeping other people safe.

[@B4its2L8guy]

When testing action vs reaction, action will always win. Always.

[@LionheartSJZ]

As someone who does historical sword fencing I can absolutely confirm that with an experienced fencer you have no chance of blocking a cut. That's why you NEVER allow anyone to get in a distance that is so close that he can hit you without having to make an additional step.

[@jnb756]

great instruction piece on being aware - if someone has a knife, unless you are a highly trained fighter with experience outside of the classroom you have very few choices... your best one is to run and if they don't follow keep running. If you are forced to fight you need a weapon to open and keep distance between you and your attacker. Chairs are excellent weapons and defensive shields, sticks, metal bar, anything that will be painful for them and not let them get inside where they can slice you to pieces. Knives are very lethal, very painful to heal from and the smallest blade can puncture a lung, kidney or spleen... again this is just for those that don't already have training - if you have fought twice in your life and you are facing a knife - run.

[@caydennguyen5250]

No wasted movement that I can see, the average person has no idea how deadly a knife can be in a criminal or in this case a well trained individual, much respect and thank you for being one of the legit practitioners on youtube.

[@kungfusansootsoilihofuthun8895]

Like the police shooting test proving action "distancing" beats reaction . The instructor stands behind you with one hand on your shoulder. His other hand throws/drops a rag infront of you. You shoot the target infront when the rag drops. He runs when the rag drops to test distance before the shot. He usually gets 10-20 feet away before reaction. Love it!

[@KevinWood44]

speaking as a lifelong martial artist...... 1. he is very fast 2. BUT no self respecting martial artist stands with his hands at his sides and challenges reaction time, speed and power with another high level martial artist. Nobody can block this, hands in a ready position (even a relaxed defensive position) I could stop this BOTH at his arm/wrist AND his shoulder. but from a hands down position its absurd to think anyone could do it

[@TheShadowlin]

KevinWood44 exactly

[@davidtapp3965]

KevinWood44 this is about the unsuspecting. its learning how to defend yourself in an everyday real life situation. tuck your head and tske the face shot

[@KevinWood44]

Kethevor Def not, thats why this isnt AS jmpressive as it seems. No human being can stop speed and power whem caught off guard esp against as experienced martial artist.

[@xomiakas]

Lifelong martial artist? What type of martial artist? Kung fu, karate and everything apart from what is used in MMA and military combat is a waste of time, so you might as well be saying that you wasted your life on some weird yoga like tai chi shit.

[@KevinWood44]

How utterly inspiring is it to see a guy in a wheelchair learning self defense. That is awesome!! What a guy 😊

[@c86alfonso]

action is faster then reaction

[@showmae8459]

Carlos Alfonso not the point

[@c86alfonso]

Showmae ok but the way the passive students are approaching the situation don't give them that much chance. 1st always keep your arms up 2nd don't just let any stranger get closer then your arms lenght. I mean really, hands to your side that's how you would approach a real life situation.

[@showmae8459]

Carlos Alfonso The fact is that while you are seing someone using that technique the effort of leaving up your arms would simply take too much time

[@c86alfonso]

Showmae I think that you have a better chance if you don't let anybody get on your space with your hands up than with your hands on the side though.

[@nightfire4107]

Carlos Alfonso My thoughts exactly

[@KyleMeyer949]

its really a great video to showcase how slow reaction times are. everyone who tried is probably fairly decent in self defence and you could see many tecniques tried. it shows how important situational awarness and going proactive if you believe there is a threat are. the reality is if someone goes full speed on you it is very hard for anyone to stop by reacting. i think that the right person may be able to block it. a combination of things mentioned in the comments would be helpfull. first keeping an eye on hands not there eyes. i also read raise your shoulder and duck your chin. that would help to shield a bit. the close hand would have to be blocking in the timeframe and you i think the ikmf krav tecnique of thowing your hips back and counterattacking at the same time with the other hand would help. all of this done by an incredible practitioner might be able to do it

[@tigereye1589]

at 1:15 you can se he is making the measurement , you can cleary see he is standing close to the MDS letters but once they start 1:40, he already has closed the distance by a whole foot while the other guy hasnt moved an inch ,wich is why his arm is bent while cutting ,sneaky tricks used to appear fair while making sure to lower the chances of the other guys reaction.

[@Radimusdepirate]

Action will always beat reaction if he is in measure you are going to get cut. There is not enough time for your brain to process the movement and react

[@CraigSummers]

James Adamo exactly! Maybe from a defensive position with hands up but not from a neutral stance as in the drill.

[@ArizonaTengu]

Need to create distance.

[@Radimusdepirate]

mryupjup while it is possible to beat someone on a draw in reaction it would require the person reacting to be faster at drawing their firearm or for the first person to fumble or otherwise loose the initiative

[@hcmpeyang5682]

Pre-cue already had a lot of studies in Sport skills. One Key clue, the cutter always look down first then attack. So his eyes wont leak the sign of attack.

[@frizz422]

youre talking about 'reflex' reflex can be/is faster than reaction ..in the sense youre talking about. being able to fine tune youre reflex to shoot a gun accurately..not sure if thats possible/beyond my understanding.

[@batpotjie5611]

Very simplistic. Much more complicated in real life. True, action faster than reaction in perfect circumstances.

[@TheLawnCareNut]

I'm that fast when I cut my lawn too - no one can stop me.

[@brankoposa1941]

That excercise is exactly the same as a surprise king hit.As distance timing plays a huge part during an attack.A great learning excercise based on reality

[@RockIslandAuctionCompany]

Saw a similar demonstration given by a stand-up fighter regarding telegraphing punches. Neat stuff.

[@fredinandethebull2266]

SPEED.Wins every time. Speed generates power & "most" people forget this. Everyone I train wants power first & they learn fast, speed generates power. very nice video.

[@normanhayashi]

That move is very similar to Systema. The trick is to move from your hips if you want to match his speed and power. All of the participants were relying on a single arm's speed and power which is no match for an attack that uses the whole body. I've tried boxing once, and the instructor didn't want me in the class because he thought I was too weak for boxing. I proved him wrong by adjusting my posture and delivering blows after blows by focusing on my hip movement. Later on I found out that there is already a few martial arts that have been emphasizing hip movement. Good to see an extraordinary performance of speed attacking. Also you will need a calm, alpha brainwave state of mind to catch the speed of his movement and react accordingly. It will probably take years of training to block that attack as it is fair to assume that he took many years of training to move that fast and add great power on top of it.

[@Jstn8156]

He did that last guy dirty because he blocked it.

[@fernzilla3766]

To all those watching. I'm the last dude who managed to block the knife attack. So I've read comments about this exercise some negative and a few of y'all praising me for blocking so I'm flattered lol. I've been an avid Kenpo practioner for 5 years and now its more MCMAP because im a Marine. Crazy looking back at this clip 3 years ago I was still fairly new to the martial arts game. If anyone has any questions about my experience feel free to ask.

[@XKeNdLeX]

Man you're rough with your students! 😱 the last guys poor neck 🙈

[@fernzilla3766]

Yeah my neck was red af

[@CommonSenseFishing209]

a simple shoulder lift will defeat that attack. instead of trying to block or move your hands or body all one has to do is lift the shoulder up while tilting neck down and sideways essentially closing the opening leaving only the side of the face or shoulder exposed.

[@TheShadowlin]

first change distance, second read shoulder. if you try to actually block you have to go above the elbow not for forearm. bicep moves at half the speed. but the key is to be there already.. of course IRL no one waits for you to say OK. I like this challenge we're going to replicate it at my school next quarter.

[@timkindred3225]

Self protection isn't a tickling competition I like the look of his work

[@PelaelOjo]

On one of your videos, you showed several and very effective block to that challenge. Hope one day to be able to accept one when ever i am in town.

[@jasonwright5195]

I like these videos.aikido is what I have studied. whom ever moves first usually wins. surprisingly no one stepped forward or back

[@Taterbean8]

The fastest way to block this attack is to swiftly lift your upper arm, allowing to to cover your entire neck. You can also swiftly move your fore arm up against your neck and use an extended hand so you have less wind resistance, using a clenched fist will make your arm slower.

[@CaptJaipreetJoshi]

Reaction will always be slower than action , its like trying to save a penalty shootout in soccer - instincts or safe distance .

[@TheOpenlot]

The reasoning behind when he creates the distance and have you put your hands at your sides is because no one walks around on guard 100% of the time. So if by meaning of true malicious intent a trained professional can kill you or commit permanent arterial damage and walk away as is if nothing happened. The eye can only identify that there is movement not the complex trajectory of that movement. Which makes blocking the the attacker virtually impossible. The biggest mistake for the opponent is to focus on the eyes of the attacker and would be better off looking at tip of the blade or the waistline of the attacker. So, if you already know where the attacker (in this situation) is going to attack, one option is to conceal the point of contact which you already know is the left side of your neck. The moment you say ok you then prepare to reach up , keeping you arm (opposite the area of attack) close to your body immediately covering the strike point and retaliating with a back fist to the attackers face. Yes you will have your hand sliced however, better your hand than the big arteries in your neck. So protect the neck with the hand and instantly attack, then create distance. In a knife fight you will always get cut so you must manage what you are willing to take and in order to survive it.

[@leftturnaudio5678]

It can't be blocked due to reaction time. Once he strikes, by the time you realize he is coming at you, you can't beat him or back up. This happens in a split second. Kind of like dropping a dollar bill between someone's fingers, it passes thru before they can clamp their fingers.

[@notayoutuberjohn]

Possible solution might be looking at his chin. His cuts might be non telegraphic, but if you look at his chin your peripheral vision will notice one of the shoulder being in a different state than the other shoulder. The shoulder that is attached to the arm that is doing the cutting will most likely move and your peripheral vision will notice it. This method would probably work the best since his stance reveals the complete front of the body, you will notice something change when he is about to strike, unless his non-telegraphing skill is that of Bruce Lee

[@3Zeddy2]

Awesome idea there at the beginning. An idea is to have a face shield present. I think more might be willing to participate in that.

[@3Zeddy2]

or, rubber knife, or "very plastic", that is better idea.

[@paulg6340]

Awesome, that third guy actually blocked one, impressive. Good on him.

[@HienaMonteiro]

[@fcsdps6593]

move forward and left arm up on the inside, also makes for a good counter. wrap your arm around his elbow and then you can break his arm or face plant him to the ground. don't move back because they can easily lean in and close that distance you just made.

[@hardtarget-avoidingviolenc5460]

It's not Mastro's ability or technique that ensures he's getting the cut here. It's that they are within the Reactionary Gap, touching range without having to step forward. First man to move / act will land his attack almost without fail. This is why sucker punches are so dangerous, etc. If you flipped the script and let the attendees stand in the same range and try to cut him under the same rules, most of them would likely succeed.

[@jhonatanhuamanperalta1992]

Buen trabajo, practico todos los dias, muy buen aporte

[@peterconaghan8869]

what is the solution left arm up. step to the right? keep a angle and hit from the left.., (that the theory, based on the knife threat) putting that into practice needs spacial awareness, and motion.. but seeing the knife should you be using angles to minimize the threat ,and a open hand to strike in defence never and never a fist and that minimises your ability .. I'm quite old. and love sparring. we in the UK always respect and learn from our opponents. that's how you get better, never be a know it all. my grandad taught me the ultimate surprise move, its a double, stand on their moving balance foot, and at the same time take them doan , as they are off balance and for that 1 second are open.

[@yearofthemetalboar5645]

A (real) encounter is about distance. In the "challenge" the distance has been bridged already and the outcome is a given especially, when the attacker is a seasoned street survivalist.

[@bodhisattva99]

It's interesting to see the mindset of people who are concerned about having their throats cut.

[@backbison]

don't think, feel. that is the answer. Tim tacket talks about responding to inclinations of attack. before the attack is initiated you respond.

[@sheldonamante9498]

out of stillness the knifer uses the element of surprise so of course the attack will have a higher success rate. reality is if the unarmed opponent sees the knife before hand, he would' nt stand so close and would try to keep a safer measure away from the knife attacker.

[@DarthTwilight]

Imagine Fred walking up behind you at an ATM..."Give me your money; jus' for fun."

[@garyjohnson9037]

rule number one, never stand within striking distance when facing a known armed opponent with a knife or some other weapon. it's a loosing battle in most cases. if you must, get very close, in my opinion and experience...facing an armed opponent in a survival situation, what would be your recommendation?

[@uwotm8]

Charge at him and duck. Either rugby tackle or turn back to knife whilst charging so barge him with shoulder and get a cheeky elbow in if possible. Worst case scenario is a slash to the shoulder, head or back (much better than neck).

[@tripplewhipper]

a simple demonstration to show the space between a movement and a reaction which is a good eye opener, practical representation of a real situation? i don't think so and I'm sure its not meant to be by mr. master either. If you don't already have your hands up as a cautionary defence then anyone and their cousin could catch you, the trick is seeing the potential for an altercation, gauging threats and analyzing it all before the threat reaches you, had the people started with their arms up in a guard situation it would be a very different story. point is if you're not aware of a situation before it reaches you at force good luck, which is often what you see in videos of altercations, someone is approached and without having a simple guard ready when the situation is coming to light, they are left in a tight corner and more often than not it ends badly for them. train to see ahead and intercept before the threat becomes a reality.

[@demetriuspooleswagdaslik75]

Master maestro the problem is there trying to block the knife versus the forearm or even jamming the shoulders the best thing to do is minimize the attack or negate it and since you cannot negate steel get out of the way the guy blocking with his forearm was excellent he just used the wrong arm.

[@MauricioKarren]

[@Megames2012]

[@ramoncorrea5716]

I think most people are missing the point. It didn't just have to be a knife. It could be a slap or any sucker punch from that range. Yes you can talk about having your hands up because you are not that stupid. The point is that we are not invincable nor unstoppable. As martial artist we become arrogant and think we have an answer for everything. This thinking puts us at risk if we ever get into a confrontation. If you think you can block the attack go to one of his seminars and get it on video. Walk your talk. OSU!

[@blazerman61]

love the love in the room there!!

[@eggyolk1814]

everyone is recommending backing off and create distance or blocking with another body part, but I wonder what would happen if you leaned in for a headbutt or something. leaning in would put you out of the blades way and wouldn't be something the enemy would expect. but of course this goes against instinct in an unprepared moment. leaning back to dodge is much slower and blocking with arms only works if you are much faster than the opponent to stop the momentum of his attack. the boxer shoulder shrug idea is pretty good, but you still get hurt.

[@eggyolk1814]

also leaning in has less overall movement. from the attackers view the face is just getting bigger xD. by the time the attacker realises, he won't have time to pull his hand back. keep in mind that as the attacker, he is already focussed on the neck. if the neck moves further, he can adjust slightly. if it moves towards the attacker, it's much harder to anticipate and adjust.

[@qmachado6555]

[@ghall7975]

In math, the shortest distance between 2 points is a straight line. Fred is coming straight in then cutting. You will never be fast enough. You must move back.

[@reginaldwelkin]

I find it interesting that only one person reacted every time. The others seem to have mentally given up, not even reacting after being hit. Also, I think everyone is looking at his eyes, rather than his hands, shoulder, or knife.

[@scottmorgan133]

Say "ok" and step forward and to the right. He made it an easy set up for himself to not get blocked. None of these participants are smart enough to consider taking his angle away. Speed and power can be overcome by getting close to threat and messing up his 'angle'.

[@RabidWolf1966]

Simply have your hands UP, not down at your side, and I say it's possible. I took knife fighting. Number one rule, don't get in a knife fight, because you will get cut. But, if you have no choice, keep your hands in a defensive position. It's much better to take a cut on your hand or arm than to get your throat cut or stabbed

[@David_Downs]

I think this perfectly sums up that "Remember that thing called bio-mechanical cutting? I said the major problem with it is on the legal front, but, on the "a knife is going to do a shitload of damage to you" front there's a lot to be said for it. What amazes me is that some people can talk about the damage that their knife will do to an attacker, but at the same time blurt out the old cliche ?of "expect to get cut" as though getting cut were only a minor inconvenience. HELLO! Wake up and smell the coffee!!!!!Where I really hit the roof on this mindset is when I see someone who comes from a empty hand fighting system attempt to "fight" an armed opponent in the same way that he would an unarmed opponent. The thing is, these same people are the ones who often talk about "expecting to get cut." And then, having said that, they take no effective measures to prevent it from happening! I have literally seen such people wade into a cuisine-art.Now who ever came up with that term originally was speaking about a very important idea. That is that you will be cut in a blade altercation and that you need not to panic when it happens and that you must continue on to the best of your abilities in order to increase your chances of survival. To that intent and meaning I say "Amen!" I couldn't agree more. However, like the idea of bio mechanical cutting has been bastardized by people into a dangerous misconception, so has this one. In fact, from having watched people who study so-called "blade arts" many of them have apparently taken it to mean allow yourself to be sliced up, making no effective defensive moves in order to try to get in one good hit. Apparently, if you nick him once to his twenty seven slashes, it is an acceptable exchange rate. The other side of the pendulum swing is however, overly focusing on trying to control his knife arm before entering. Hanging back and trying to catch this fast moving blade so you can safely enter is one of the best ways I know to make getting cut a self-fulfilling prophecy. This is what really results from trying to extend a "fighting mindset" into weapons combat. It simply just does not work. Would you like to hear our philosophy on this subject?Trade a cut for a kill, but nothing else. That's the difference between fighting and combat." found here: www.nononsenseselfdefense.com/knifelies.html#LaCoste

[@David_Downs]

Unlikely if under the same terms and conditions Fred gives everyone else... as this is a test of the reaction gap... action always beats reaction, you simply wont have enough time to react to this cut in time to avoid it in most cases, especially not at this distance and with your hands down, it is pretty much impossible in that regard to block, this makes it look easier as the knife is a trainer, so no one is getting cut or harmed... but against a live blade, the results would be different.

[@bucket415]

What about stepping in immediately? Get past the knife. I really don't know. I'm just trying to think of a solution.

[@dustinbaconflipper]

Jon Williams Was thinking of the same thing, literally lunge yourself forward at him. But there's a fundamental at play here: reaction. By the time your brain processes the threat, it's already cut you.

[@Flintshadow]

you could watch his shoulder to see when the muscle flexes... don't know if that would help. i guess you could also fall away or... huh it's a really simple knife strike but really hard to counter...

[@David_Downs]

not be there ;)

[@carlitoapplecool]

Solution is to keep your hands up when being confronted like this, or create more distance. There is no need ever to let anyone so close unless you think he/she will give u a blowjob. Knife attackers need short distance. Someone comes at you, you tell him to go away, put your hands up, maybe step back a bit. If he doesnt listen, you kick the shit out of him, if you miss, at least you have your hands up and you can block those cuts and work from there. If someone has a knife and is THAT close, it means you fucked up on a few self defence principles already.

[@David_Downs]

carlitoapplecool If your hands are up, he goes low. No one on the streets is ever going to attack like this anyone. They wont let you see the knife at all, you probably wont know the have it, and the attack wont come like this, it will more likely come from low point. If you put your hands up, you will be attacked in the stomach. It doesn't matter what at this range, you never get into it. This is sucker punch range, where the reaction gap comes into play. The reason people are sucker punched is because action will always move faster than reaction, and if your opponent doesn't telegraph his strike, then you wont react fast enough if dont know when an attack is coming.

[@fusazzo94]

I would like to see Sifu Sergio Iadarola doing this challenge! That would be interesting!

[@sdfarmer64]

why not, you ask? or is because of you neuromuscular system and the 0.3 seconds it takes you to react. like the "$100 bill challenge", there is not enough distance to allow you to react in time to prevent the cutting. when I say 0.3 seconds, that's for the highest caliber, baseball players, pro drag racers. The absolute fastest of the fast cannot respond any faster than 0.3 seconds. They know he's going to attack the neck, imagine if they had no clue....

[@AARIONTHOMAS]

I know the moves really fast but would it be a little better defense to move in closer

[@SciSciToys]

Okay lets do this again, this time I have my hands up, so I have time to react, now see if the knifeman will slit my throat, in a real fight you don't have your hands down and allow the person to come so close AND if you can't see his fingers then you definitely move and put hands up.

[@JSRLPadre]

Of course not! It is just about action and reaction. So almost complete BS in my opinion. The only thing you can learn from "his famous knife cut": Everything can happen (fast) within an arms reach. But that is not really that new!

"It’s just for fun. . . " not for application

[@ChrisKsan]

You're missing the point... Go train and you will eventually find it!

[@jaminsim5965]

That's why it's a block challenge

[@shanek6582]

I wonder which way of sharpening a knife would cut better, one sharpened razor sharp but down to like a 10,000 grit stone with a mirror finished edge, or one sharpened razor sharp but with a courser stone?

[@MTknives]

I prefer a toothy edge so stop at say 800-1000 grit Japanese Waterstone, When I am processing meat like deer that is all I do.

[@shanek6582]

That's kind of what I'm thinking. I usually sharpen my pocket knife to a mirror edge but I've never tested to see if I need to go down that far.

[@shanek6582]

I do cut into the stone but I also use a leather strop, and I pull it on the strop. So my knives will stay sharper longer if I don't use a strop? Or even a buffing wheel? Thanks. I met a guy selling knives at a gun show and he sharpened his knives on a belt grinder and went on and on about how his knives stayed sharp and cut longer because of the microscopic serrations.

[@pierrelarouge]

If in bad situation is always best to strike first, if someone is armed & you are not is nothing wrong with just kicking them straight in balls.

In México, where I can to learn it?

When will Fred Mastro come to the S.F. CA.?

[@jordanhorst6]

forgive my ignorance but why did they all try blocking from a standing still position with there arms by their sides? The way we train is to turn at our shoulders an hips while ducking then with both arms up, thrust up into in the arm/armpit of the attacker. All in one motion. Im not saying my skill is at all fast enough block that. but it seems to me like they weren't using their full range of motion.

[@jordanhorst6]

Ok, still he should move with his whole body. Move forward and away. And then turn into opponent.

[@orbandavid5072]

jordan horst Good point, but in REALITY its much harder to do that all the motion you're talking about. That is a complex movement for the brain, and in a real situation the attacker does only one fast movement. You have to be really good to block this. Anyway, I understand your view, and I agree with it. However, If I would stand there, I would pull up my hands at the time I saw there is a knife there. After I'd say ok...

[@jordanhorst6]

Orban David yes true but, in training we were taught to move with are legs first. not our hands. :) your right of course, its incredibly difficult to perform complex movements under duress. I merely noticed that they responded by raising their hands and almost cowering back in on themselves.

[@orbandavid5072]

Well you may learn systema I guess then. What exactly the reason you move from the legs? I want to join a class but haven't done that yet. Actually why I got suprised watching this video is because the master didn't give any solution to this knife attack...

[@jordanhorst6]

Orban David its better not to be in a single position when blocking. if you move forward or into your opponent or away and to the side at least you have a chance. Although this methodology varies between different disciplines.

[@rcp8287]

its called reactionary space! anyone can do it, you can even have the person put both hands up in a ready position and they still cant block it!!!its not because he is fast! its because he can touch you! anyone can do it to anyone! just make sure you can touch them,like he kept doing .

[@hanumarn7882]

In real life, if I see a guy holding a knife, I wouldn't be standing that close to him anyway.

[@feirabbitt]

so could I kick to distract so that could get out of the way or attack first before he strikes .

[@dpeshy6719]

has the guy shown what he proposes one does to defend/protect against a slash like that? I know that if anyone (a stranger) comes to you within the steiking range you don't stand with your hands down.

[@puravidadew7031]

the mannequins coming up to him are keeping their bloody arms to their side not ready not prepared asleep at the wheel

[@delarosapatraygabriels9789]

what a fast hand over here xD
