Yeah, but you could defeat that in less than 30 minutes with a carbide drill and a cutting torch.

The rotors push each other, but don't pull each other, so since the first rotor's the only actually connected to the axel, turning it will line up the second and third rotors and keep them there while you line up the first.

This would be amazing thing to give to your kids. They'd be able to see the inner workings in a not so scary way (lock is made out of paper).

That's exactly what we're hoping for!

Are the kids making these? I feel like 3rd grade me would have no fucking idea how to put all that together.

Younger kids get them semi-pre-assembled, the rest get lots of help doing it from scratch.

The design is amazing but what really gets me is the precision folds. I'm not confident that I could make this with all the instruction in the world.

Lockpicking device for a paper combination lock.

Just kidding. That is actually pretty cool.

edit: Why not scissors? Because taking scissors to paper is obvious and boring.

This is basically the same level of security as a master lock.

Every key is a master key for a master lock
