The Assassins Creed Hidden Dagger

Altair ,the protagonist of the game Assassins Creed has a hidden dagger attached to his arm which is obviously spring loaded, but he unsheaths it by pressing a button with his pinky and retracts it with the same. I wanted to know if it is possible to make such a contraption and how it would work just to satisfy my curiosity. There are a number of videos on youtube but most of them are gravity driven or do not give any explaination so I'd be obliged if someone helped me out with this.

Exactly, but according to the makers of the game say that stuff actually existed + if im not wrong, someone actually managed to make one. As per the legal issues - I dont want to make it, I just want to know how it works.( it could be modified to help in some sleight of hand tricks)
No, I watched an interview I down loaded from Xbox live about the game(as I'm equally interested in the hidden dagger as you are, it would appear)and the lady who thought the whole idea up(who was quite hot by the way)said that where certain aspects of the game are very much true(leap of death for example)and others are entirely fictional like the dagger(she said to make the game more interesting), plus apparently according to her they had to cut off your middle finger, which I'm not really willing to do. Good topic though, I was going to post something similar myself. I was thinking maybe compressed air to propel it outwards, but then how would it retract? Also have you ever seen those telescopic batons you can get? You have to really smash them off a hard surface to get the buggers back in, so you could stab something with it if you sharpened the head into a fine point and secured it to your arm, just getting it back in though.

Yeah that lady is hot but i was thinking that maybe its partly gravity driven so that when he press the button it falls out and gets stuck on some sorta hook and when he presses the buton again a spring pulls the dagger back or something of that sort.
u guys have good ideas like urs for example but i made one that was gravity driven and i found out that u dont really need the button to make it come out as much as u need it to go back in i mean ive been pondering the same thing as well and the same types of assassins are still around but ive been thinking what if when altair pulls his hand back the blade slides out gets latched onto the sides of the slider and when he presses the button then it goes back in because the gravity driven one i made i can sling my hand back and push forward and the blade stays out. Pondering it well im thinking that may be just maybe when the button is held down it pushes a latch which stops a gear that has maybe like rubber rope or sumthing to that matter that have loops at the end attached to each end of the gear when the gear is hit it pulls a stopper on the side of the blade up thus propelling the blade upwards then when the rubber rope or wutever is bunjeed into it slips off the other rubber part is already attached by how long each rubber rope is until it reaches the top then it is pushed into a crevace stuck until u r ready to use it again but the gear has to have enough ends to make sure that after it pulls the blade up it resets in the same position but you would need a winder for another gear so that it could make the other gear move i mean it sounds simple enough but the clockwork idea is good but what do you think of mine
I like it! sounds feasible enough, make a Instructable!
kk ill try but i found another guy whos real close to making one to
What about CO2 driven to go out, and spring loaded to return?
sounds reasonable but were trying to figure out how to make one with out a source of forced energy which ud have to replace
Ok, I gotcha. Probably the best you could do would be a spring to open, that disengages when the blade snaps into place, followed by a weaker spring to close it. You'd have to reset it after every open/close cycle. Anything beyond that (short of clockwork, or motorized) would be approaching perpetual motion, which is obviously a no-no.
switch blade...
