Dual-Action Hidden Blade 3D Model

The video shows the assembly sequence. Here are a few notes on the steps: The shell should be smooth and flat on the inside The blade needs to slide freely in the shell The latches are placed to lock the blade in the retracted and extended positions. They should bend out of the way as the blade moves and then snap into place The kicks need to slide freely in their slot, and are under tension with a rubber band between them With the slide in place holding the kicks apart, the device will start to work. Move the slide forward to extend the blade, backwards to retract Rotation of the cam moves the slide forward and back The triggering line needs to be strong and thin. I used 26-gauge stranded wire. There are two bumps in the line, one to catch in the cam and another to stop the line from retracting too far. I used small bits of metal tubing clamped to the wire. The line needs to be fixed at the back end with a small rubber band or spring to make it retract after use. The other end is attached to a ring on the user's finger
