4 in 2 is a difficult level 14.17 puzzle. The box is split into two halves, which have unique internal protrusions.

Great looking puzzle that's not too challenging.

The cog moves up and down the track but due to varying lengths of teeth and varying sizes of holes, the movement is sometimes restricted. The cog is also capable of being rotatated 180 degrees and thus allowing further moves to occur.

Nice little wooden lock designed by Robert Yarger and made by Eric Fuller in 2017.Eric's original comments :Robert and I have talked about reproducing some of his older work for a while. He sent me a few designs and this lock really grabbed me. Originally a component on his Pirate's Wallet puzzle box, he had many requests for the lock alone.

There are 1-2 minute chips. The lock is generally in a very good condition and was given a careful polis...
