Blade Firing K'nex Knife
Intro: Blade Firing K'nex Knife
This instructable is on how to make a knife which can fire its blade. Useful when you are down to a knife when your opponent still has a gun, you can lull them into a false sense of security muahahaha! It can also fire small pellets.
I am not going to say 'it is my first instructable so be nice' because i hate it when people say that, so feel free to say so if it is rubbish. However, i do not want people saying bad things about k'nex in general.
Enjoy,
Knexguy
