Folding handcuffs

The idea behind this project was to make a small portable pair of handcuffs that would be strong enough to hold someone for a short amount of time. I don't think i would trust my life to them but if you have nothing else they do work.

You will need 18 m3 x 8mm and 1 m3 x 30mm bolts and 19 m3 nuts to assemble the handcuffs you will also need a small spring an old pen spring works well.

I really appreciate your feedback so if you have any questions about this project or ideas to improve it
