How To: Create a spring loaded hidden arm blade from Assassin's Creed for your movie

i love it so evil >:)

i need the size of the bolts and nuts and the spring size too

If you can't figure that out on your own, then you probably shouldn't build it. ..you posted this 4 years ago...you could be dead by now and. It even exist ..probably talking to a dead guy

my question is would there be a way to do the same thing only backwards so the blade could shot back in

you went to fast wanna do the same thing in slow motion lol.

ok i'm gonna need to do 2 things. 1 save my money, and 2 suck up to my dad for help! I am SO makeing this for a cosplay/convenion. And as for only useing it on a closed set, i am very comfortable so i am consiquently very safty concious about knives and practice safe handeling quite a bit. and if my dad helps me make it, he wouldt even let me hold it unless he was absolutly confident it was safe.

im making this toy!

If you use it like a toy one of your friends is going to get hurt

I love this!! I can't wait to start. Thank God my dads an engineer so he can help me.

Hey I thought this video was excellent in detailing the process. I was interested in doing this for this years Halloween I thought it would also be a fun project with my dad! Thank you for the list of materials needed, process and safety it's exactly what I was looking for and hopefully I can be a part time assassin this year!

I know A MORE SIMPLE way to make a hidden blade.
Note : IT may not to accurate in visual, but it works good!
