One thing to keep in mind about extendable batons is that they're effectively one time use if they're actually used. Sure you can extend and retract them freely but if they're actually used to strike they often bend. Once bent they can be forced to retract again but then they don't freely extend. This is something police accept as "expendable". Your sword might have to take the same thing into consideration. If it's used in self defense it may effectively not be "reusable" but served its purpose.

[@pkonneker]

I've never heard that before. Makes sense I guess. Better the baton than you

[@Rafaela_S.]

As far as I know it depends on the quality, what you hit and how much force you use, for example hitting the thighs still hurts enough to stop someone, but it will be soft enough to do no damage to your baton. Some even come with a 2-year guarantee, which explicit state that what is not covered is: "gross damage caused by strikes against hard objects (e.g. stone, concrete, steel)" meaning that you can get a new one for free, if it is unusable after using it against a human/animal.

[@patrickhenry8425]

They are ones with a heavy spring with a weight for the tip. They don't bend as the spring absorbs the shock.

[@green7449]

Idk, I have an extendable baton that’ll smash right through cinderblocks without bending.

[@SgtSly]

I’ve been in law enforcement for five years and I’ve never heard anyone say that a baton is an expendable item. Sure, they break on occasion, but I’d be pretty pissed if they broke under common use. Everything breaks. Our squads and pistols break, but that doesn’t make them expendable items. I’ve had an Asp Talon for most of my career and it has busted through many car windows and other hard objects with nothing but scratches. But, for Shad and Tyranth; the Asp Talon is a perfect example of a telescopic design with a button lock that will keep it extended during a thrusting motion. Most batons are friction locks, and I’ve had other officers use my baton and try to close it by banging it on the concrete like they would a standard issue one. It has stood up to the abuse.

[@Alkaris]

Consider the following; Take how Umbrellas function with their retractable pole, you can have interlocking latches that you have to push into the blade to retract the blade, and you just use a kind of spring mechanic inside the blade itself that locks everything in place. So you'll have to choose where these interlocking latches are on the blade and make room for it on the blade. The thickness of the steel and spring should make it a pretty solid modern sword for a retractable telescopic design.

[@ankokuraven]

So a thought to consider is to not solely retract into the handle. You could have a very small sheath so your blades could be a little longer than your handle. It would potentially reduce the segment number, which would make it stronger.

Hey shad! Consider contacting Adam Savage, host of mythbusters, in his channel Tested. He is a precision machinist and i bet he will be able to not only create but also improve any design if he agrees to work on it.

[@Kio_Kurashi]

I imagine money might be the issue there. Unless Adam just wants to help out from passion and not charge top dollar (naturally there'd still be some costs, and the fact that they're both popular youtubers would mean there's some content to be made from it) to our still-probably-suffering-from-the-algorithm Shadenites.

[@randomkoreanguy]

This is a great idea. It would probably help sell him on it if you pitch it as a proof of concept test to see if it'll even work properly as a durable blade and they could run Mythbusters style tests on it to see how it holds up compared to a standard blade against various things like a flesh analogue, types of armor, types of shields, etc. You could make a video creating the sword from Adam's side, and then have Shad do the Mythbusters style durability tests.

[@rgemail]

I assume Adam *could* build this, but this kind of metalwork isn't really his specialty. This design would either need to be welded up from machined halves or, possibly, cut on a wire EDM. Who knows, worst case if he has any interest at all would be he recommends some good machinist contacts. The problem I see is the cost to setup for machining one of these and finding out it fails quickly. You could also get it printed in steel for prototyping 'sake, though obviously the strength would hardly be a 1:1 with solid metal.

[@xxdwbxx]

This is a subject I love. Collapsing and expanding weapons are one of my favorite things and I like having them in the stories I write. The big one is in my fantasy medieval story where the Royal Families and their Royal Family Knights have these weapons called Expand Weapons (Not completely attached to the name) They are easy because it’s magic. The casing of the weapons hold a pocket dimension inside that holds all the blades, cross guards, handles or shafts. So when they’re fully expanded they’re even stronger than regular weapons, because magic.

Put a solid knife on the end of a sturdy extending pole/stick that gets to sword-length. This forms a mini-spear that might even have some cutting potential. You're obsessed with "sword" because that's awesome, but "mini-spear" might actually be practical.

[@natethornnstuff1783]

I agree. There’s a reason swords have stayed in one typical form despite many style variations. They work well for their use and too varied of designs don’t do the sword job as well. This design I think there would be too many areas for stress to multiply and break the whole thing.

[@TheBanedHero]

''Titans of CNC'' could probably do this using EDM.

[@ryanbecquer3496]

Shad. Engineer here. I highly recommend you look into the Gerber Doubledown or the Atropos balisword demon. The balisong style folding lock is very very strong (at large scale you can even do intermeshing gears or have a significant tang section held by the handles. It falls into the category of blades that would be as long as the handles (or longer with an extension like Joerg Spraves folding machetes if you want to save weight and add length) but it doesn't suffer any of the thrusting collapsing issues that telescopic designs or an OTF can have. I have it on very good authority that a lot of locking designs were tested for this sort of mid-range larger-than-a-knife but machete/large-bladed camp tool (or wakizashi-esque profile in the case of the demon) size blade and the balisong lockup won. You can also have a significantly thicker blade than your handles might suggest once held which is a downside of the telescopic design where the handle must be and remain larger than all the segments once deployed. This is present in the double down because folded it's only slightly wider than the blade but unfolded what were cutouts revealing the blade become a grip profile that can essentially be as small as you want. Just avoid making it way too high of an aspect ratio and from soft materials like Filipino baliswords which are much more prone to breaking. It also is significantly more practical to manufacture. It's still difficult but you don't have all the insane internal geometry of the telescopic system it's just a couple channels cut and a relatively standard blade.

[@Pystro]

Good idea. Usually people make folding mechanisms for these things that rely on a single sturdy articulation point and a comparatively flimsy catch/latch (I say "usually", but I think I've only ever seen Njord Artisan actually attempting a folding sword). The balisong gets its stability from the fact that it uses 2 equally strong articulation points (at a considerable distance) to hold the blade piece. (While the direction perpendicular to the blade is constrained by the design of the hinge points themselves.) It would even be possible to improve on that principle by offsetting the 2 articulation points on the blade (putting one further forward than the other). That would give you even greater stiffness against bending in one of the directions. (Put the blade of the sword on the side with the further forwards articulation point.) And the two handle piece surfaces that meet when the blade is unfolded should be machined/structured in a way that they mesh together, in order to avoid them sliding against each other. I think it should even be possible to make a 3-section balisong sword by using that "intermeshing surfaces" technique on both of the meeting surfaces - and you'd need some way to keep the pieces at the rear articulation area together. Obviously the articulation "area" where the singular front section meets the two middle sections will get in the way of it fully working like a sword, so it might be better to think about it as a spear/glaive with an added sharp section on the front part of the haft. But a 3-section balisong seems like it would have the added advantages of unfolding even easier than a 2-sectioned one, since you don't have to turn the handle pieces inside out; and the advantage of it being easier to get the handle section to align in both the folded and unfolded arrangements when you significantly offset the hinge points forwards/backwards.

[@Pystro]

Also, in case anyone else wants to marvel at Joerg's creation: kzbin.info/www/bejne/gKWqh6ediJWDj6M

[@snakefabel]

i think if i was going to design an extendable sword, my first thought would be to have a shorter blade with an above average length handle, such that about half the blade would be able to retract into the handle, and then have a sheath that goes over the rest of the blade and clips onto the handle to keep it in place. you'd still be able to get good reach with the length of the handle but it would also be able to shrink by maybe a quarter of it's total length. depending on the size of sword you want that could pretty easily be concealed under the flap of a jacket.

The classic Shadiversity 3d model video.

[@Will_Forge]

Hey Shad, crazy idea from an American, and I know "make it explode/combust" is an accurate depiction of our mentality with weapons, but... Imagine an extendable sword that doesn't go back in afterward and maintains perfect rigidity by igniting some small chemical pockets that are designed to automatically tac-weld it together the moment it finishes extending. The blade would weld itself to the handle, and the blade segments together, and where you hold the blade would be made of heat resistant silicates akin to those used to make oven mitts. This kind of extendable sword would be a worst case scenario weapon for someone defending a structure with tight corridors such as a bunker, spaceship, or cave network rather than a weapon you'd regularly want to carry around. Very sci-fi rather than fantasy. Anyway, I'd love to hear what you guys think at Shadiversity about the idea!

[@tyler1o1o16]

I think if you did an otf blade that folds in half you could theoretically have a secondary otf mechanism for a pin of some kind (preferably rectangular for better durability) to create rigidity. The primary difficulty of this design would likely be incorporating the second otf mechanism. I've always wanted to make something like this as a proof of concept I just don't have the tools to do it yet.

[@hozimina]

My favorite version of the "collapsible sword" is a plate-pinch design. This contains two plates that are angled and hollow as well as solid hardened tip that can fit inside. How this works is the hollow plates are being held by tension via the handle they can hide into and the tip is shaped so the base of it has a shaped knob that gets stuck inside the two hollows. This sword is gravity/momentum extension style and because of the the tension in the handle it actually holds well.

"It is weird for someone to wear a sword." 🤨 COMING FROM THE MAIN HOST OF A SWORD AND MEDIEVAL CHANNEL!?

[@JarieSuicune]

He does say "is weird" not "was weird". In context of the present time, yes it is weird for someone to wear a sword. The only time an average person probably wouldn't be surprised to see that is either a cosplay, actor, enthusiast, or similar situation. And that's assuming that it was obvious that such a role was in action. (In contrast, it generally isn't very weird for someone to wear a gun in the modern day.) If I understand correctly, swords in general are not illegal to bear but are subject to the same laws as any other tool that is explicitly a weapon. However, there may be an amplified implication of threat imposed by carrying a sword due to how the injuries caused by a sword are quite large and more visible compared to that of a gun and thus feel more scary than a gun. Although a gun will almost certainly be more lethal in any given encounter due to considerably greater range than a melee weapon and being equally deadly at close and longer ranges (being close enough to interfere with aiming doesn't make the gun less deadly, it just may reduce/increase the chance of you being hit by the bullets) with enough power to reliably one-shot-kill anyone or just spray multiple shots per second and kill via sheer amount of damage to the body (depending on model), guns have sadly become normalized in the public consciousness whereas swords may be viewed as an active threat of brutal harm: "Of course you carry an unobtrusive gun that I likely won't notice, it is 'only' for self-defense" vs "Why would you wear a (comparatively) bulky/awkward sword if you don't intend to attack someone in the first place?" May be a contrast of perception of threat due to visibility and pseudo-lethalness, I guess? Maybe like, you hold a gun and think, "oh, this is a gun but it isn't dangerous if I don't pull the trigger" vs holding an unsheathed sword and think "yikes, this sword is likely sharp and dangerous to everything, with just an accidental swing I could severely harm or kill someone!". Or something like that? I dunno, I'm no expert, it's just my observations. Anyways, none of that is to say that swords aren't quite deadly as well, only that in the end it "is weird for someone to wear a sword" in the modern day.

For all the various opinions about it, the Ultraviolet movie does this really well. Both Violet and the main bad guy have swords that can extend from a basic hilt. It works through the tech that I like to call "flat-space" storage. The difference between those swords and Shads design is the Ultraviolet versions are one solid blade. The extension mechanism itself that's stored inside the hilt also acts as the bracing and support to keep the blade in-line and prevent it from buckling at the point where blade meets hilt. Probably through having a MUCH longer blade and only extending around two-thirds or even just half of it outwards. The back-end of the blade would probably have something like a geared mechanism to extend, retract, and lock the blade in place, which would be far more structurally secure than just having a collapsing baton-style blade. Of course, now that I think about it, the other possibility is that they all just carry regular solid swords and just keep them inside flat-space storage until pulling them out for fighting, hammerspace-style. Personally, I prefer the first method. :D Violet is actually able to carry a HUGE amount of weapons in these little bracelets she wears on her wrists. It actually becomes something of a plot point when she walks into a security checkpoint and the scan reveals a virtual ARSENAL of weapons while the security guys just stare at her with jaws dropped.

I think this is awesome! And it could definitely work! :) I feel like Tyanth has a difficult time giving Shad the credit he deserves sometimes. Looking forward to seeing more on this!

[@EduardoJusto01]

Great video as always! I'm no enginner, just a random thought about keeping a foldable blade with structure: What about a wire with tension? Held with a electric motor or something... Not possible in medieval times, but with today's tech?

[@kleinjahr]

Probably want a monomolecular wire, though that is a bit difficult to source.

[@Nathan-vt1jz]

I like the new merch!

[@Sawtooth44]

this would be something that the Hacksmith workshop might be able to create

[@Gandalf22476]

Great idea! Also love the hoodies!

[@micky8ball]

I love those hoodies!

[@v1p-3r]

Hmm, Forge flat, then fold then pieces over to keep them hollow? would be hard to get the internal structure consistent (or hard to machine the inside of theses. Maybe machine out the core or each section, then weld the spine back in after?

[@mgancarzjr]

Use a mandrel to keep the internal form

[@ricodave]

Very hard to machine with precision. I wonder if you could press it though... As it's such thin section. Problem being the joining of the two parts without welding etc. maybe with a dummy internal former...

[@lars9168]

These hoodies look really good! Might grab one :D

[@alizomenta3801]

I just love shads excitement.

[@JerehmiaBoaz]

You could use a steel wire running along the length of the blade to keep its telescopic or hinged sections under tension, the tension should activate a mechanism to lock the telescopic sections into place or keep the hinges fully extended. You'd put a simple lever mechanism on the hilt to put a lot of tension on the wire (imagine something like a lockable bicycle brake handle on the hilt that could potentially double as a hand guard).

[@tabull8180]

Sounds good in theory, but how much tension (=force) are we talking about here? Given enough force, wouldn't that essentially be a spring loaded grenade if anything breaks?

[@JerehmiaBoaz]

@@tabull8180 The amount of force depends on the locking mechanism. Assuming it's a telescopic blade the mechanism would be something on the inside that either extends a force outward to friction-lock two telescopic sections together, extends small locking bolts through two sections to lock them, or both. You'd spring load the mechanism so it unlocks automatically if it isn't under tension. I'd imagine a few hundred Newtons of force on the wire would be (more than) enough, and if the system fails it would implode and retract the blade rather than explode.

[@tabull8180]

@@JerehmiaBoaz Thanks for clarification. Thinking about more, the breaking part issue is something that any desing have to be very aware. Essentially I was already thinking about the worst scenarion, but the whole point of this video is rather how make something that could actually be good and robust enough to work. You don't build something expecting it to fail. Overall your idea isn't too bad at all.

[@Kuna_music]

Why don’t you try reaching out to the hacksmith and see if they can make it for you?

[@MalachiH-dw7vd]

Yeah! That seems within their wheelhouse.

[@CyberChrist]

Great merch idea ^^ Oh, glad Icy Mike got a shout out \o/

[@jierdareisa4313]

I love ALL Shadiversity videos!!!! ❤

[@gvstaden1]

🗡

[@nucleonegro9762]

If i had enough money i'd grab three brigandine hoodies: one as a gift to one of my brothers, another one to keep the way it is and the third one to experiment and see if i can transform into an actual brigandine

[@TheHawkhead1HunterK]

Hoodies look awesome guys! I put in an order right away

[@JohnStrider778]

I always love just how blunt they are to each other about disagreeing and still manage to make such great content with different opinions

[@TruthSpeaker893]

Omg I need it. Yes thank you so gonna try to grab 1.

[@ModelLights]

From using a telescoping pole for cleaning and similar tasks, leave more than you think inside each joint. If you extend the sections fully, there is 100% torque on the joints, more angle develops, and it's easy to break them. If you leave about 6" within the previous section the forces are more side to side within the joint, the extra length left inside the previous section stops it from being able to develop such a high torque right at the joint and break the joint. 16 foot telescoping paint pole etc at Lowe's in the USA for reference for the type of pole. But most any telescoping pole or antenna works similarly, if you leave a reasonable bit back within the previous section it is much stronger than fully extended.

[@evanjohnson5038]

I love how Shad just starts to go off (because he's so exited and passionate), and then Tyrant keeps things together and moving 😂 Love seeing the creativity, keep it up!

[@BUZZKILLJRJR]

Those hoods are awesome!!

[@seymourfields3613]

Having carried an ASP (extendable baton) for my years moonlighting as a security officer, I can confirm they hold tight when you extend them with commitment. So well, in fact, that you can actually jab at someone's chest (specifically top of the ribs and the clavicle area) with it and it won't loosen. With a blade, you would be aiming for a soft area if you're forced to use it to defend yourself or another. To collapse them, I actually had to hold it in a reserve grip and hit it into the ground with a "hammer fist" type motion. A baton, however, is much thicker than a sword. I don't see that design working for a sword with any length to speak of. Maybe a blade twice as long as the handle? The more layers you add, the worse it will operate in the end.

[@C-Henry]

A few examples I can think of, U.S. pilots in WWII were occasionally issued a folding machete, and the Italians did something similar with a folding bayonet. Both of these had the blade extend from the handle when folded, it was just a slightly shorter package. Also currently for sale in the U.S. is a butterfly knife style folding machete offer by a company named Gerber Gear (not to be confused with the baby food company). All of these are limited in how compact they can be by the length of the blade of course, but they are the best real world examples I have seen.

[@worldkeyvideo9080]

Enjoyed the enthusiasm

[@eetadakimasu]

Love the banter😂

[@user-yv4mm6bx3c]

I've wondered about the plausibility for an extending sword for a couple decades, but I always just assumed it was more fantasy.

[@dustinmillar120]

The hoodies look great guys!

[@Nekoyashiki-san]

Thanks for sharing your passion and lets see if internet will do its magic of putting peoples together. ^^

[@knightfall91]

Oh he'll yeah I've pre ordered one might not fit but gives me something to work towards plus it helps you put and looks awesome

[@Brixujel_Rimulex]

3:03 owning one of these makes his reaction to it expanding 3x as hilarious because not only are they both flexable and durable but they are fully capable of nailing someone in the crouch. how i haven't been on the receiving end both times i watched it happen is nothing short of a blessing...

[@KeeseGaming]

I'm excited to see the carbon fiber sword. I've been waiting for it for what feels like forever!

[@xBrokenMirror2010x]

I think the issue with the idea of a collapsible sword for self defense is "why?" On a fleshy target, as you were talking about, a pocket-knife will easily be more than enough, and the engineering tolerances of a pocket knife are much lower, and as such, the costs will be lower. The complexity of engineering a collapsible sword likely has this costing more than a gun. You've now ended up in the ballpark of "Well, if it's going to cost more than a gun, why wouldn't I use a gun?" and the answer is that a gun is better, period. This is also why, technologically, we don't spend time as a society improving the sword, because the niche for swords is a tiny niche, a collectors market, and collectors are more likely to want pieces with art, or historical, value, not "modern advancement" value. While I think it's cool conceptually, there is absolutely no market to sell this too outside of the hyper niche "modern sword nerd." Now on the actual design you showed. I think the interior structure of the pieces is too complex. Creating precise hollow shapes like that is not trivial. If you could design it to be an entirely simple interior, either totally rectangular or circular, it would greatly increase the viability of manufacturing. You should also accept that something like this would be 100% consumable. Once this is actually used to attack something, it's going to bend, and it will not be fixable by a normal user. Just accept this as a reality to cut costs further. A self defense tool does not need to be reusable. Once you've defended yourself, you're alive and safe, you can simply buy another. If you need to defend yourself every day against multiple attacks and require a self defense tool capable of being used many times throughout a week, you should just invest in a gun, because if you live somewhere where you can be attacked 2+ times a week, you probably should own one.

[@brook_sabin]

This seems like it would be right up the alley of the Stuff Made Here KZbin channel. He’s got all the tools, the brains, and the willingness to do sketchy stuff 😆

[@beskamir5977]

When I thought of this, I also did it in the context of lightsabers, and I ended up with a few ideas. One was to lock the extensions in place with some kind of internal spring system to prevent them from being pushed back in. Then pulling the springs inward with some kind of string running up the length of the blade would allow the blade to be pulled back into the hilt. The other option was an active support solution using electromagnets, though I suppose normal magnets or inflating a tube with a liquid or even a gas could also work. If it's an electromagnet setup then you'd need to provide energy to keep the blade from falling back together. For the more passive case you'd need to have a container to store the gas/liquid at a higher pressure, then use that to inflate your sword to lock it into place, and then eventually move that substance back to wherever you kept it (or to just vent it out) to allow for the blade to collapse. While regular magnets would be about the same as relying purely on friction. They'd just be another barrier to prevent the blade from easily collapsing, but that'd also make pulling everything back together extremely difficult. Another active support option would be to constantly blast something at the top of the blade from the hilt. This would be sort of like using a gas or liquid at high pressure, but it'd be a constant cycle and thus the pressure would be more strongly focused at the very tip of the blade keeping everything from falling in during a stab. The obvious option for this would be to use water in a very similar way to how a pressure washer can be used to push something away. The more advanced version of this would be a particle accelerator within the handle and a decelerator along the length of the blade before it'd give the particles just enough energy to fall back toward the hilt to then repeat the cycle. We don't really have the tech for the more advanced option, but an active support based on pressurized water should work. Ultimately, I think the problem here is making something that's collapsible, but still capable of retaining it's expanded shape for the entire duration of the fight. We could try to solve that with purely compressive strength of the material as your design assumes... or we could try to solve it with tensile strength of the material by using something else to ensure the material remains maximally stretch out during the entire fight. I suspect it'll be easiest to go with the tensile approach.

[@TheWadetube]

Good job on the design. I think it could perform in between each of your estimates as a light weight weapon. Difficult to make, yes, perhaps a lost wax casting would work. Precision is a must and polishing even the inner surface would be necessary. You could make the tip piece and perhaps the handle and the first section but the second and third would be quite a challenge. 3D printing might one day be an option but it would still need to be polished on the inside. Good luck.

[@Zainenn]

That sweater is AWESOME!

[@reichstein011]

I have one of those telescopic rods, and I have found that it makes a serviceable pool cue if you give it a bit of a twist after opening it. Doing so tightens the shaft a fair bit and makes it pretty solid. While I still wouldn't swing it at someone, it could make a functional emergency stabbing weapon if you added a sharp point to the end. I also found that applying a little bit of tension to the bottom of the "staff" prevents it from loosening and becoming less rigid. This can be done by just holding the bottom/wide end, or by wrapping something around it to prevent it from expanding.

[@lancemurdoc6744]

I as an engineer see 2 possible ways to make this. A electric discharge mashine would be the cheapest technik, but it would take quite a lot of time and the low thickness could cause problems. But I would test it. The second technik would be a 3D printing System...but this is quite expensive.

[@andrzejsamorzewski146]

I'm pretty sure it can be done with EDM, the smallest cavity that fit final segment is 1mm well with what can be done. Currently 3D printing makes to rough surface for this application.

[@erickkisreal9398]

there are some 3d printers that can print metal

[@u.v.s.5583]

Traditional Japanese sword masters made these things by hand. They took the void, put the steel along the void and hammered until they had the segment.

[@Jet-lx8uh]

This is. Really neat concept! Perhaps it would be even more possible if the amount of segments were reduced? I'm thinking something like a 2 and a half handed or 3 handed sword (think the LOTR elven swords). That would mean each segment could have significant length while the handle alone is still very manageable in size (just bordering the limit of manageable) With that you could get a similar length with only 2 blade segments, and maybe having the hollow parts be thicker? Perhaps the strong of the blade would even be able to be supported in the middle with some pins or beams, while the top would have a central cutout, but would still be a solid piece. The other nice part is that if you wanted your folding cross guard. You could still grab the grip of the sword without impeding the deployment because of the length. This would probably be a more scimitar/Messer design given the inspiration and possibly would allow for the segmented blade to be balanced by having a more effective taper than a double edge. Possibly would even add strength

[@rhileyjones7092]

Njord Artisan has done all this stuff its really cool he even tests it and stuff!

[@johnblackdeuce]

With an extending design could use the pop out buttons similar to the ones on the legs of folding tents
