Here are the nut crackers- not my design, John Economaki of Bridge City Tool Works is the designer. In the picture below is one of his on the top, one I made in the middle and on the bottom, one in progress. Mine are too thin on the bottom and don’t look as good as his- my turning skill needs more work so I don’t need to sand as much!
FYI, he had published the instructions on a blog for people to make for personal use.
