WOODEN COMBINATION LOCK
This is a wooden lock made from poplar. It's most effective on a different planet where there are no saws or sharp pocket knives. I remember having a toy plastic lock from a cereal box when I was little. It had 3 dials, but it was very easy to open. You could turn the bottom dial until the lock opened 1/3 of the way; then you could turn the middle dial until it opened 2/3 of the the way; and then you could turn the last dial until the lock opened all the way. I didn't trust it with my valuables!
I made sure this lock wouldn't open until all the dials simultaneously were in their correct positions. I put 4 little pins inside instead of 1, so even if 1 pin was aligned with a slot, it wouldn't move if the other 3 pins weren't aligned with their slots. In order for the dials to rest on top of each other, and not occupy the same space as the pins I hollowed out the dials so they were like little upside down cups.
