Balistic knife v0.1 (first prototype)

This is the first prototype for a balistic knife, inteded as a prop. 

The trigger mechanism isn't the best and may not always function as intended, if you hold it down it should retain the blade but as soon as you release pressure it fires, otherwise i found out testing (was not intended) the if you lift the trigger all the way it can retain the blade quite well.

Maybe in the future i will update new versions but it may require a long time.

It requires 2 springs ( i used 5.5x25.5 mm as shown in the picture) and if desired it can be assembled either with nuts and bolts or with simple duct tape (in my print i used both).

Assembly should be intuitive, springs attached to handle and piston on both sides, put the trigger in the slot, screw everything (or tape), insert blade, have fun.
