How To : Make A Manual Knife An Automatic Knife ("Stiletto","Switchblade" & "Switch Knife")

[@Wrenchmonkey1]

Just FYI, fewer coils means more power. The more coils, the more spring 'area' (for lack of knowledge of the technical term) there is to concentrate the energy in, and it becomes more dispersed. Fewer coils means more concentrated energy, and more 'explosive' response. Hopefully that makes sense, and is useful to you.

[@JDStone20]

Great video! Just last night I found a small purple (under 2" blade) auto in my closest, and the action was terrible, so I did some maintenance and now smooth like butter!

[@petearon1027]

That model Schrade is _not_ already milled to receive a coil spring if you're trying to convert it into an automatic. The part of the frame that needs to be removed can be seen in the video between 2:55 and 3:00 minutes. A rotary tool and a grinding bit can be used to remove the excess aluminum quickly and then the spring can be added without having to cut it down and bend it, etcetcetc. Once done properly the knife works very well and has a hard, solid kick when deployed.

[@mich5167]

do you know if this can be down with the gerber propel down range?

[@petearon1027]

I wouldn't know first-hand, Michael, but switchbladekits.com sells the parts you'd need to convert one to automatic. Here's a link: www.switchbladekits.com/index.php?l=product_list&m=12

[@mich5167]

+Pete Aron 150? is that for the knife and the kit?

[@petearon1027]

Yea, that's spendy, I agree. It shows that it's possible, though. Google other stores, you may be able to find the parts for less.

[@TofranBohk]

You forgot to have "Take care" in your closing. How am I supposed to know what to do now!? :-O

[@philoubilou]

Hi, Writing to you from french riviera. Thanks for this video, you just gave me an innovant idea for an automatic system. I gonna watch your others videos.

[@drunkinmaster1]

The coil springs are actually easy to make. You make them on a lathe using piano wire and a spring arbor. Run the lathe just like you're making threads as it wraps around the spring arbor.

[@MattTyrrell]

Or just buy a handful cheap online...

[@ApeFahrenheit]

Because everyone just has piano wire, a spring arbor and a lathe laying around...

[@drunkinmaster1]

You are correct. You can always buy some springs for fairly cheap because that is the easy way. But some people ( like myself ) enjoy doing things myself. Btw, piano wire is not expensive. You can use a cordless drill instead of a lathe. A spring arbor is simply a piece of round stock with a hole drilled.

[@thewolfchild]

+drunkinmaster1 Well, since you can't make cordless drills by yourself (and enjoy doing so), we're back to just buying a couple of cheap springs online...

[@justgus3164]

Cheers for this video Cutty. Switch blades are illegal here in the U.K.. its where I purchased my favourite knife so going to have a go at converting that x

[@bigrich2110]

Just Gus did you try it ?

[@snowmantkmc]

what size spring did you use on this as i have the same knife and would like to do this

[@BrianMcKinny]

FYI - the next time you come upon the problem with the spring being too big, you might want to try heating up the coil spring first, before you bend/cut it. That will avoid breakage.

[@lazar2175]

Heating up a spring will destroy it.

[@adamcarson6294]

idk how many times I've been watching a video, recognize cutlerylovers voice, check and its him!

[@BenTheDream1018]

Dude the music is aweful. Cool video I took apart a smith and wessen auto before and I totally know what you mean when you say it's a pain in the ass.

[@_iso_553]

accidentally clicked this and now im on a watchlist

[@koga8100]

No you aren’t

[@richardmcginnis5344]

you wouldn't believe the money i have made doing this. i had a cheap china gas station knife that was spring assisted and i used the spring to turn a ka-bar wart hog into a spring assist. i had to find out how though so back in 2016 i looked on here found this video and its all gravy from there

[@shaanakhtar3114]

Do you have a list of knives that are like the one you converted?

[@bigfootandbananaman4746]

I have that Schrade and mine was converted by blade hq for me. I love it it's a really good knife

[@markbooth.13]

Right!! Blade hq!

[@knifeman1122]

I can say that knife is the first one I like from schrade. Loving the tanto. Also jeff missed out. When taking an auto knife apart. It has to be already opend before u un screw the knife. Or it will spring out the blade a parts out

[@NicholasAarons]

Awesome Video Jeff. Keep up the great work. Nick.

[@MikeRondeaucantinacast]

I just saw you and Guss on the science channel, the show was outrageous acts of science. Lol

[@bf898]

hahah, you can hear gus snoring in the background!

[@BLACKOPS6391]

RIP Gus

[@jonathandawson5632]

Hey im sorry if this is a stupid qustion but i had a prety nice looking automatic knife o got ofline once but in like 1-2 days it stoped working i had someone take it apart and the coil spring was messed up like streched out maybe kinda bent even my qustion is can you fix a coil spring after something like this has happened any answers gladly apreceated thank you vary much

[@The_Warrior526]

[Blade flies out] Nothin' here for you, maggot! LOL

[@codyholland8011]

Looked like it turned out great. I wouldn't have known that wasn't (factory) spring assisted.

[@bgemski]

Very nice conversion Jeff!

[@jonathandawson5632]

Hey im just wondering if you thank by chance that this can also be done with say the Milwaukie fast back 3 i believe it was that i had it had a button on it but it was just the lock but would have been over ahundred times cooler if someone could have turned it into a switchblade for me you no what i mean

[@TheKocksmanArchives]

I assume this won’t work with a regular folding knife without a button lock?

[@mentallyderanged9169]

YES 2 finger it HAHAHA, at 8:52 and 8:56 i can definitely hear it scraping. You said you could feel the drag I can hear it lol it is very audible to hear it.

[@geneosborne7857]

Hi Cutlery Lover - Schrade auto spring replacement video, I have a Schrade SC70. were does the o ring go?Thanks

[@nomadbound9610]

A stiletto is a knife or dagger with a long slender blade and needle-like point, primarily intended as a stabbing weapon

[@TheMaxxMiller]

Great video Jeff. Very informative.

[@docsmellyfella]

Coil spring looks like the sort that are in Mitchell fishing reels that flip the bail arm back on. Found plenty on ebay. Could you use these instead?

[@Zach11zzz]

Hey, I'm an electrician from Massachusetts and I found your video very interesting. I was curious if this same method could be used on a utilty knife (milwaukee fastback). If so would this be something you could create and ship to me?

[@salimbenjelloun5874]

I know I’m a year late to reply to you but i was wondering the same thing so i opened up a milwaukee fastback and figured out it is possible to do the conversion. I am planning on doing so soon

[@damienjameszimbrick]

Awsome tutorial i loved it so much i bought a new knife and some springs. However, the knife i have has (i think) torx screws and i lack the tools necessary. Any suggestions to open this knife up?

[@sea9984]

Damien Zimbrick just buy a torx set, its cheap and easy to find everywhere

[@joeloliver2279]

Where did you buy the cheap auto? I don’t want to mess up a nice blade

[@DaliwolfBacon]

I like Scrade knifes. I can USE THEM and not have to worry about busting up an expensive knife. That's a cool mod. I am going to try it :) I have American Science and Surplus right down the road from me...I am going to go see if they have springs big enough to fit my knives. :)

[@cutlerylover]

perfect :) yeah the right size coil spring is important, they are cheap to buy so maybe a few sizes to try out is a good idea to find the perfect fit

[@steveblades6967]

jeff did you make a vid how to make the spring i have the excact same model schrade and another in desert camo both were sold without springs would love to make them auto

[@jdog4534]

is that a coil spring or a torsion spring? I think its a torsion spring. they are used for torque operations . torque is twist. coil springs are for pushing (open coil) or pulling (closed coil).

[@jeremyjones3286]

I'm curious if you would try a conversion with the Buck Redpoint. It's already nice with its quick one handed action. It would be amazing converted to auto. I would sincerely appreciate it if you would give it a shot as a tutorial for me.

[@HelloHello-hk4sx]

The screws on my knife striped, had to bring it back to scheels. They were so pissed that one of the staff sold me such a crap ass knife that they gave me a different one for free! 😀 I thought they were mad at me for a second because of how fast he grabbed the bad one out of my hand. 😅 Pretty sure someone got fired or yelled at. 😏 (scheels is normally a very expensive fancy hunting store so this was unusual)

[@Spookysexyes]

Wow that shows they take pride in the quality of their knives

[@secretagent3764]

Where can a get a ouch button knife like the one you have? I think you mentioned is from China or something. I have been looking for one. Thanks

[@tomvickers6169]

Secret Agent they sell otf (out the front ) knifes on the app “WISH “. Thank me later. I have a collection now thanks to them. 💪🏻👍

[@shiestycolman732]

Have you ever tried a kershaw dimension? I am going to go all out and see if it's possible, I'm guessing not because they already have a torsion bar, so I don't know if it will have the space milled out for the spring?????

[@libreaotearoa9203]

How does the locking system work? is it the same lock for open and for closed?

[@jordanhicks5131]

Legal reasons. What legal reasons. It's a fucking pocket knife. Not a gun.

[@TheJamesB18]

can i just ask how do you afford all these top qaulity knives? what is your profession? and how long have you been collecting knives?

[@JosephWheeler14]

He has multiple jobs, been collecting knives all his life. He made a video about bringing knives to school and if I remember correctly he had multiple knives by 3rd or 4th grade.

[@dseednorwayn47]

need to do something like this cause custom keep stopping my knife orderes..good video

[@ColtonBlumhagen]

I wonder if the spring was separate from the knife when shipping if it would be fine.

[@hillbillyknifenut83]

Switchblade kits dot com ships kits , they send the spring in a separate package to international customers ;-)

[@johnandrewserranogarcia7223]

too bad I can't legally do this, I really need to move to a different area

[@tannerkelley7645]

can you use a pen spring?

[@ed2335]

Does knife have to have a lock release for this to work?

[@normanbradley2536]

The knife is still NOT legal in NYC because it can be "wrist flicked" open, as you showed, and police and courts have classified this as a gravity knife.

[@jeremyhagen7684]

Have you looked at the Milwaukee Fastback knives? Could a spring be added to the changeable blade models?

[@markbooth.13]

Has to have unlock button to open/ close.

[@TheFiendRacer]

Hey cutlery lover, I was wondering if u can do the opposite and make a push button auto into a manual.?

[@gabrielemagnabosco8926]

+TheFiendRacer the cheap chinese one he cannibalised for the spring, if you put it back again, without the spring, is now a manual knife...

[@gabrielemagnabosco8926]

+TheFiendRacer the cheap chinese one he cannibalised for the spring, if you put it back again, without the spring, is now a manual knife...

[@casehuh]

what is the name of that small tool at the top of the screen. really interested in that.

[@Augusttheknifeguy]

Would this be possible with knife like gryptilian, or sog trident

[@RoodogGonebushTas]

+August Bolin No not the gryptilian, and the Sog Trident is already spring assisted buddy

[@brandonshawn5877]

is it "plug and play" or do you need to drill the blade and the handle for the spring to work

[@markbooth.13]

No.no. no fits right in with right size spring

[@williekeith5915]

I'm in South Al we pack Glocks switchblades and Case trappers. and shotguns in our trucks

[@AskJoeTaylor]

I have a knife with a liner lock that gives way and folds up easily can you help me with how to fix it

[@MADgamer9212]

someone sleeping in the background!! LOL

[@lrpoell]

Nice video!

[@unimatrix82]

Cool video, but who is snoring in the background ?

[@thewolfchild]

What size diameter is the spring? And what size width is needed? Thanks

[@manlikegus238]

There's a name for that certain tuoenof spring. Dont suppose anyone knows what it's called?

[@peturoliver9695]

Is that frank zappa in the intro?

[@returningfaith]

That is awesome. I got an auto for $4 from a friend and I kinda want to try this on a better knife because that one is nothing amazing

[@BourbonButcher]

Hey, is there a way to swap blade from one knife to another? I have a knife that I love everything but the blade, and one that I broke and want to swap blades?

[@Jeremy-ql1or]

+GNARXiSiST If they are the exact knife, it is possible to swap the blade but if they are different models, the blades aren't going to fit on the other handles.

[@theplasticdesert2408]

Cool video mate.

[@johnnyrock723]

I really need help about how to make auto knife to manual knife

[@laroy3323]

can you buy just the coil someplace

[@hypetrooper2152]

Can this be done with a Gerber 06 manual knife?

[@PavleSavic00]

There are coil springs on Ebay

[@ultrak3ks358]

come knockup?

[@chaz64borthie]

How do you know what size of spring to buy?

[@shreddedreams]

where did you get the cheap chinese auto from ???

[@mattmaiden4920]

i have a m@p button lock would love some info on how to make auto i live in tn so its legal to carry anything auto or fixd blade

[@johnnyrock723]

Can you pls make a video about " how to make a automatic knife into an manual knife"

[@josephwoble4152]

I have been trying to buy a good knife I dont have mony and the one I have cut me because it some times locks and the blade never opens. I was wandring if you could send me a knife. Also I want to start doing videos.

[@thewolfchild]

+Joseph Woble LOL! You _must_ be joking, right? That Schrade is about 25 bucks and the spring is $1. You want him to send you a "good knife" (how about a Marfione Custom Sigil SS T/D?) for *free* so you can "make videos", yet you can afford a computer, internet access, a video camera, tools, medication, etc., etc. ...nice try, chump.

[@pathfinderLXXIV]

I'm confused. It looks to me like you converted an auto knife into... an auto knife. The Schrade you put the spring into already had the channel in the handle, hole in the blade, and button. It WAS an auto knife. If you put a spring into a regular folder then you're converting something. Still a good video to be able to see how the internals on an auto knife look.

[@apexgamer8648]

Read the description

[@nomadbound9610]

No he put the coil from a spring assisted knife in a auto knife. Pointless honestly considering the shade already comes with a coil. THE COIL THAT WAS MADE FOR IT. Just saying

[@laklander1447]

1:40 That "woo, woo" was soooo freakin' wimpy! HAHAHAHAHA!

[@michelfreeway9177]

How'd you get the button on there?????????

[@AntzZMArshiN14]

Nice video

[@undermoonlightglow]

Very well done!

[@johnycash978]

Idk but there might be plastick peace sticking there already where the spring should sit

[@bigwpg204]

What model number of Schrade is that?

[@TKO_Horticulture420]

You know this really wasn't a conversion man. This is more how to install a new spring if your old one brakes brakes. Because 90% of the conversion drilling the counterbores drilling the hole in the blade all that that's the conversion process this is just putting a spring in a already manufactured automatic knife

[@Meejhem23]

i dont like the music. the rest of the clip was very educational as always.

[@HelloHello-hk4sx]

I thought the button was for opening the knife, not closing it. 😑 I got cut. BE VERY CARFUL WITH BUTTON KNIVES!! They close very fast & hard when you push the button. Lucky I didn't get cut worse! Not a beginners knife.

[@TimurTV1]

You are the best thank you

[@jackcartier7508]

if that wasn't an auto why did have a button and not have a thumb stud, or flipper?

[@azpwnz]

I'm sure glad I live in a state that seems to think auto knives are highly dangerous and refuses to make them legal...

[@jimidp2187]

The knife I want to convert is not a push button. Does anyone know of a video that shows how to install a spring without the push button?

[@thomaspaterson6876]

where did you get the knife

[@urmomdoer2315]

I'm looking this up after looking at a school shooting PSA.

[@sttm1283]

where do i buy the manual shrade knife? im sure customs will gimme a call if i order the auto :D

[@shawnt8891]

Micke blades hq you can buy it already done for 30

[@armageddonknives]

nice, how is the centering after this?

[@cutlerylover]

off to the side, haha spring size was wrong, but wiht the right spring and a few extra teflon washers you can dial it in right

[@armageddonknives]

thanks for the reply :)

[@WH1TEDEVIL]

They used to still have them on ebay.

[@lachlansmith5320]

What is the name of that knife ?

[@MattTyrrell]

Great video, what model schrade are you using for the knife?

[@83RBurke]

Do you think a spring from a clothespin would work? They seem a little big if memory serves.

[@Jeremy-ql1or]

+83RBurke The springs from clothespins and chip-clips won't work for this kind of knife as they are too small. They actually work for the FB humpback coils and the older KC humpbacks (although, you have to go through a lot of chip-clips to find the right size one). You can get a coil like the one in the video from a number of different supply sites. I think Jantz has them. If not, send them a message and ask them where to get one.

[@danklovell8104]

What knife is that in specific?

[@LPXDproductions]

I Currently can't do this legally where i live now but i will be moving to a free'er state soon where Auto's are legal

[@TheSk8metal]

I live in Norway, I own a lot of nunchakus, shurikens, butterfly knives and other spring-assisted knives. I'm not gonna carry any of those around, so there's no reason to be afraid of the law. The rules surrounding knives and other weapons are just fucked up, on many levels. The only somewhat ''valid'' reason why butterfly-knives and spring assisted knives are non-legal to posess, is that they can be opened with one hand... But, holy anally-raped nugget, I can open non-assisted folding knives with one hand, and I don't even need to open up a kitchen knife! I got pockets long enough to put a kitchen knife in, I just need some duct-tape, and I'm ready to go!

[@LPXDproductions]

Jesus guys all i was saying is that i can't have auto knives where i live currently i understand i can break the law and buy and make what ever i wan't but i'm not going to, now when i move to Arizona where everything is legal i will most definitely be buying and making tons of Autos.

[@TheSk8metal]

Do it anyways! Molotov cocktails and homemade sniper-rifles! Snort speed and hail satan!

[@TheSk8metal]

Oh... You might be right

[@chimeraaaaa_]

***** Same, but in Canada

[@gt0915]

LOL yep i did that I brought 80 of them 20 @ 4 different sizes and strengths.

[@turtleman190]

were did you get the springs

[@gt0915]
