Sry if there already a thread about this I couldn't find any

I always thought it was relatively easy to do and so I never paid too much attention to it. Then, to save the work of designing one by myself, I went to the internet searching for way to do the hidden blade and I was surprised to see none could retract.

I'm not talking about Ezio's hidden blade (activated by a muscle in your arm), that's just ridiculous (imagine Ezio hugging Sofia then accidentally activates the hidden blade...somehow. Uuuuups), I'm talking about Altar's hidden blade, activated by a wire.

My questions is, is it really impossible to do a retractable hidden blade? I don't think so but I'm yet to prove that

Imagine if you pull the wire, you activate a spring and the blade comes out, if you pull it again, you deactivate that spring and activate another that puts the blade back in place. Is this really impossible? I couldn't find anyone doing this.

Well the problem with that system is that both springs still need to be reset for the next use of the hidden blade.

From what Iv'e seen in the codex, it looks like the blade uses a siscor-link system, to make a real version, you could use a similar system, that also uses springs that get compressed when the mechanism is activated and the blade extended, then when the trigger is released, the springs extend, and compress the mechanism which retracts the blade.

Hey guys, I'm actually a member of the Sinza forums (Username: Hidden-Blade)

Yes, it is completely possible, look up Ammnra, he's made one, I'm working on making one too, problem is, Ammnra's and my design are using a Dual Action Out The Front (DAOTF) switchblade design.

I know that the AC original design uses a scissor jack, the problem with scissor jacks is that they're very weak and very stiff. Again, alot of people try to use "Coil springs" in their designs which is basically a piece of spring steel made into a coil shape, again the problem is that these move very fast, making it hard to make a catch to lock it.

If you wish to talk more about it, please join the forums and private message me, if you're serious about making a replica, read through all of the posts (I've made a huge thread on there called "Analysing Ammnra's hidden blade" which explains how Ammnra's blade works!)

Plus, is there a way to change your user name?

Thanks!

Wow, that's absolutely awesome. So it's all possible, even with activation by a muscle in the arm alone?

Well, I have tinkered around with that idea, but it is very flawed, I'm a Cosplayer who just so happens to love weapons. I'm a bit of a perfectionist, but I've soon realised it's out of the question. The ring string on the other hand is very possible!

In the case of Ammnra's blade, he uses a pulley mechanism, with a small arm connected to it.

So, as the string is pulled, a knot on the string catches on a pulley, rotating it, a spring then pulls the string back. With this circular motion, an arm also rotates with the pulley, look up "Scotch Yoke" mechanism on Youtube, it shows rotating disk (circular motion) which then moves a bar forwards and backwards (linear motion) this is like the holy grail, it's what is needed to activate the DAOTF mechanism.

There is a slider in a DAOTF that activates the blade etc, you need the linear motion to push and pull this slider forward.

So the pulling of the string, creates circular motion, which is then converted to linear motion with the scotch yoke mechanism, activating the blade.

You may also want to look up how a DAOTF switch blade works on Youtube.

Also, is making a new account against the rules? I really want to change my username. http://forums.ubi.com/images/smilies/53.gif

@Light_Rey I was thinking like you have a spring that is deactivated when the blade is down and another that's activated, pushing it down. When you pull the thread, it deactivates the spring that was pushing the blade down and activate the other that pulls it up.

Anyway can you send some videos? I'd like to see that working. Thx anyway, I just wanna see if it is really possible, just curiosity xD

Two way springs don't work, they balance out, and finding a way of automatically unhooking one would make it too bulky.

Not necessarily. If one spring has significantly more energy stored in it when contracted it will work, but only once. After that the springs need to be reset.

Maybe make it with a small "generator". Lazzy to check for the right name, but ya know, like clocks, etc...

Ah I get what you mean. So basically making a mechanism that needs to be mechanically "recharged", like a wind-up clock. That might actually be possible.

So you're talking about a coil spring...

A coil spring will give off a circular motion, not like the extension springs you're on about which will use a linear motion. If you do the ol' make one compression spring stronger than the other weaker compression spring going the other way, they'll balance out.

You can use a spring retract, inertia extend if you don't want the fuss of a DAOTF, check out Abonude on youtube, he's got a good intertia blade.
