Hidden Blade Mechanics

[omega 616]

While that would be cool, it's to complicated. The more complex a mechanism is, the more chance of failing. Also during Altäirs Regina, he changed the design so they did not need to remove the finger.

Mechanically, this is not plausible.

Edit: The finger muscle flex, that is.

Altair never changed it, Leonardo da Vinci did, theres a even a rather funny scene were Leonardo plays a small prank on Ezio.

 

[TheSeventhLoneWolf]

I would've just said it'd activate after a certain tensing of some muscle, but meh. I've read the other posts.

 

[eTe]

I am pretty sure Altair changed the design, Leonardo mentioned it in that very scene you mentioned.

 

[phinus]

question that wasn't answered, sure the idea of how it opened is simple, but how does it retract? it's not like he pushed it in like a fake lightsaber, is shot back in.

 

[Julianking93]

I always thought there was a little button on the underside of it that they push into their hip to make it come out.

 

[Svizzara]

I'm not very familiar with the weapon, but it's perfectly plausible...

Behind the blade is a tension-loaded object that naturally wants to pop forward, such as a spring. There is also another, strong object in front of the blade that is preventing it from popping forward (acting as a barrier). When the user flicks a switch which is connected to the object in front of the blade, the barrier is dragged out of the way, and the blade pops forward due to the spring. When the user wants to conceal the blade again, he flicks the switch back into its original position, pushing the barrier back into its blocking position while simultaneously pushing the blade back into position, and it's hidden again.

That's a generic idea. A switchblade would be a specific, and probably more accurate example.

Yea they usually just remove the finger. In fact in creed 2 Leonardo jokes with Ezio when he gives him the blade about having to remove his finger.

Being a prick, and being a realist are two completely different things. I only used extreme examples to prove a very simple point: It's a game. This object can be rationalized in numerous ways, none more true than the next (Within reason.) If he seriously can't conceieve a way for this contraption to work, he shouldn't be playing an M rated game. Ultimately though, it doesn't need to be rationalized. Why? Because it's a damn video game.

i agree "Being a prick, and being a realist are two completely different things. "
but your not a realist. I am a realist and this is a very real contraption it not a very easy one either. "if he seriously can't conceive a way for this contraption to work, he shouldn't be playing an M rated game." i wouldn't say that it took me nearly 8 months to get this right and even then it sometimes wont return. you may talk critically about others when you yourself surpass them. if you can come up with a full prove plan of how to build this then games probably don't entertain you. i for one would love to hear your plans on how to build this. and if you think it has no place in society then your an idiot this has major military applications if a soldier could hide a flick out blade close quarters would be much easier. that 12 inch survival knife is hard to hide even for a seal. he would never have to try so hard with a device like this.

You could either give it an incredibly high velocity, or use magnetic fields to hold it together and be released on impact.

Just to quote a nice writeup on the subject [http://stardestroyer.net/Empire/Essays/PlasmaWeapons.html] from Stardestroyer.net:

OK, why don't we try solving this problem by using a much lower-energy plasma with increased density? We could try to solve the buoyancy problem by making it colder (say, 1 eV, or 8000K, which is a bit hotter than the surface of the Sun), thus necessitating a thousand times more ions in the same volume, but its density would still be much too low to push it through the atmosphere on momentum alone. It wouldn't necessarily float up, but try throwing a balloon at someone and you can see how well an object with atmospheric density would fly if hurled at the target.

No, if you want it to push its way through atmosphere on momentum, it must be either much denser than air or moving at extreme velocity, which sci-fi plasma weapons generally do not (and which would make it more of a particle beam than a traditional sci-fi "plasma weapon"). So what if we decrease the volume to make it as dense as a solid projectile? Well, that takes care of the "can't push its way through atmosphere" problem, but now you have to make it tiny, and in order to do that, you need to squeeze it with immense pressure. If we squeeze our 1MJ plasmoid into a 1cc volume and apply the ideal gas law (which is a good model for plasmas), we find that the pressure is in the range of 700 GPa! When you consider the fact that this is a thousand times greater than the yield strength of high-grade steel, you can begin to see the problem.

How many problems arise when you need a containment field a thousand times stronger than steel just to hold your plasmoid together? Some questions leap to mind, such as "if they can create such a strong containment field which somehow supports itself and doesn't even need a projector device, then why can't they make personal shields as strong or even stronger?" One would also have to ask why it doesn't glow like the Sun, since it would be hotter than the Sun's photosphere and denser than steel. And finally, one would have to ask what the point is of this whole speculation, since our plasma "bullet" is now denser than aluminum and should act like a real bullet now, which means it should drop in gravity. While that may not be an insurmountable hurdle for a hypothetical sci-fi weapon, it certainly doesn't match the sci-fi weapons we know, which do not arc noticeably in gravity.

In conclusion, the idea of a slowly moving self-contained plasmoid weapon simply doesn't make any sense. Your "bolt" is constantly trying to blow itself apart on the way to the target, you must invent some kind of ridiculously strong yet easy-to-run containment field to make it hold together (thus raising obvious questions about why this super containment technology is not used to effortlessly protect against these bolts), and when it finally does hit the target and the mythical "containment field" shatters, the barely-contained ions within will promptly scatter in all directions, thus wasting the majority of their energy by dissipating harmlessly into space. Even those ions that do strike the surface of the target will achieve poor penetration; most of their kinetic energy is randomized rather than being directed forward, and the gas cloud lacks the characteristics which would allow it to push through solid armour rather than simply heating its surface. And after all that, the plasmoid won't move in a straight line the way they're invariably shown in sci-fi; it should arc downward in gravity.

u know to much. we will find you O.O

 

[darth pookie]

As u can see by the rest of the people,u will pull a ring activating the blade to push through the conraption.But,created by leonardo da vinci it was ment to be carefully planted inside the wrist,sacrificing your middle finger so the blade may realese through to kill the "Victim".i dont know about u but sign me up.

 

[berault]

Believe it or not, there is several videos on how to build on of these with a bunch of different ways to activate it on youtube

 

[assassain96]

it's very simple how the hidden blade works there is a thumb ring witch mean when he cut off his ring finger it lets him pull a thread it triggers the blade and it comes out in three diffrerent blades how i know all this is me and my friend aremakeing hidden blades but when he does pull his hand it pulls the thread witchjust slings the blade out

 

[dthvirus]

Don't know if anyone here read Broken Sky, but there's a hidden forearm blade in that series that is extended by knocking your elbows together. Probably not the safest release mechanism, but it sure looks cool drawing them together.

 

[Montydew]

So I think just about everybody here is familiar with the hidden blade by now. If not, then let me enlighten you- the hidden blade is the weapon used by Altair and Ezio in the Assassin's Creed franchise in order to pull off quick, stealthy, one-hit kills on unaware enemies. It is quite a cool tool and is iconic for the series, not to mention that it is perfectly possible to create a hidden blade in real life, except for one thing. I may just have missed something here, but does anybody else wonder how exactly one makes a hidden blade "fire"? Do Altair and Ezio just press a button we can't see and the blade comes out of its compartment? This seems to make sense, but in every screenshot I see of Ezio exposing his hidden blade, his hands are bare, with no "firing mechanism" attached to the vambrace which holds the deadly weapon. Also, how does one assure that a hidden blade doesn't misfire and take off two or three of the user's fingers? These may be minor complaints, but I'm seriously wondering how exactly hidden blades function.

Any thoughts?

If you notice, whenever Ezio or Altair stab someone with the hidden blade, they have to pull back their wrist. The Motion of the wrist sets off a trigger in the hidden blade that pushes out the blade. In the earlier model with altair, the blade placed so close to the ring finger and just in the right position so that it would cut it clean off if used without the sacrifice of the ring finger. This symbolizes loyalty.

Thanks for the backup. =D

 

[connor wants to know]

if any one knows how to actual make one out of metal could someone email me the plans and tutorial for how to make it for a costume im making my email is [email protected]

i would be gratfull very and if any one esle wants to make one and succeds tell me thank you

oh can it be so that i dnt have to lose a finger it would be nice and if it could be retracable that would be cool but dnt worry bout that

Heheheh quick-draw toothbrush, replace it with a blade and BAM! Hidden Blade!!!

Buy the new Just Cause 2. They seem to have ripped off that mechanic in a vambrace, and it even looks like the same technology even though it's thousands of years after, but hey...

 

[Inv3ent0r]

Maybe if someone would be intrested and is smart enough, i do have a possible design for the hidden blade,,
only too bad it excists of very litle parts... you never know.. ask me

 

[Veldt Falsetto]

No one else pay attention to this?
