Sam's Sheathe and If it's possible in real life.

[Rickerus]

Just a fun question. Would Sam's Sheathe even be functional in real life. And if one could make it.

[rudeboy]

I'm no engineer, but I'd say absolutely yes.
The mechanism itself is simple, though it may end up being bulkier in reality, and you would likely not have anywhere the same power as Sam's(if it did, it would likely rip your arm off on the draw, or at the very least dislocate it.)

[Rickerus]

But how would the mechanism work?

[rudeboy]

Gunpowder? Compressed Gas? Nano-machines?

IDK lol. Like I said, not an engineer, but the concept itself isn't any different from a gun or cannon. The problem would be designing it to fulfill the function while A. Not ripping the wielders non-cyborg arms off on draw. and B. Looking and functioning aesthetically like a sword/sheathe

Modern technology probably can't do both of those at the same time. Anything we build would probably either be too large/heavy, at least if you want power anywhere close to Sam's ability.

You could probably build a neat replica that could cover both those points, but it would literally just be a toy/prop. I still can't imagine it looking very aesthetically pleasing though. Since either way you're going to need to make everything larger to fit whatever mechanism you use.

Nah, i am not asking the question directly to you. As this is a thread, but i could see your point. IF this is possible, i am thinking of something that is not as powerful as Sam's. In the DLC. He also seems to be able to use it even without the Cyborg Arm.

[Alcyreues]

I'd say it's plausible; I just don't think most engineers who would pull it off would want to do it because it isn't really practical. If we're talking for things like cosplay it probably wouldn't be as hard with lighter materials and a spring loaded release mechanism.

[ramonpontes]

It could be done, it is very common in many toys (Nerf?). A similar pneumatic system could work, with some heavy adjustment, of course.

But as stated in the very first reply, a normal arm could not handle efficiently the ejected sword, and would probably injury the user. Also the Sheathe would be too heavy to be usable during a fight, unless the user is a cyborg.

[KeyKey]

Rather in a weaker stance. It is able, you could just modify a sheath and put a spring into it with enough power to burst out the sword. But don't expect your sword to throw these red effects as well
I'm rather referring to a toy like sword

Even without the cyborg arm, he was still wearing that suit/exoskeleton, and when he shot that "cop" in the dlc story, it had enough power to launch the guy in the air...

But since you said that it doesnt need to be as powerfull as the one sam uses, yeah, you could do it.
If you were going to do it with a blade like the one sam uses, a "katana" I think?(although I think sam's sword is a little longer than a normal katana) then the curve in the blade may be a problem if we go for some insane speeds, but the curve isn't really that big for something more "realistic", so, we could still go for it.
Now, the problem comes when you think about how much "power" you want it to have. I'm no physicist, but while a katana may look like something very light(1.1kg or more), launching that 1kg at high speeds may be a little problematic, especially if you were going to do it with only one hand...

I once thought about cosplaying as him, and even though I knew it would be very hard to make his exoskeleton with every detail, the thing that really bothered me the most was which material to use for the sword, I mean, it had to be light, to make it easier for launching at a decent speed and to not hurt anyone, but also, it had to be very durable, so it wouldn't break or bend after a few uses.

He DOES use his cyborg arm go grab the sword. MAybe it has more grip and faster response time than a standard arm.

[Dr. Gori]

Could it work? No. But this is Kojima world so it could function on made up tech that ignores normal rules of reality.

I figure the sheath operates like a ram accelerator. Basically the base of the sheath would use high-pressure gas ignition to fire the sword sub-sonically into a specially shaped upper chamber (scramjet) filled with various gases that the sword (projectile) burns to increase its speed and ejects at the speed of a bullet. This would account for the sword being red hot after ejecting, the gas venting from the sheath and the force it ejects. The top of the sword seals the chamber completely before going into combat.

The problems are the reinforced sheath would be too heavy for a non-cyborg, the force would rip a non-cyborg arm off, the sheath isn't physically long enough, we don't have powerful enough accelerators currently for the sword to reach fast enough speeds, the sword is a very poor shape for ballistics, no one besides the military would be able to pressurize the gas into the sheath, it would be super expensive and you would only be able to do this once at the start of a fight to unsheath the sword.

[Jet Mystery Torpedo]

Here's an idea. What if the sheath of the sword were to use electromagnets and be basically a miniature railgun with a sword instead of a bullet? It would still suffer the weight and bulkiness that people have previously mentioned as well as the user having to carry a lot of heavy duty battery packs to provide enough power. However, it would create the speed that we see in game and it would also allow the user to perform a lot more shots in rapid succession than other methods (air, gunpowder).

[Chieth Kieth]

you guys are all coming up with weirdo tech when you can clearly see in the level-0 cutscene that there's just a rod that fires out and hits the crossguard to push it out.

[mavneto (real)]

I know he uses Blanks to shot the bar forward thus launching the blade but that's all I really know about it's workings

[That's it buddy]

It’s just a piston that shoots out, so yes, absolutely, the sheath can be made in real life. The trigger most likely releases a high tension spring which sends the piston forward into the Katana’s hilt, ejecting it out of the sheath

[kingkaizoku85]

I have a strange idea but im no engineer. What if we used magnets? Like make the tip of the sword charged (which is easy if its a ferrum metal, just run a magnet across) and then inside of the sheath, have a magnet that will repell the tip. By triggering the trigger, the magnet gets pushed by a mechanism into place. Right where it would be needed to have an effect.
