These are other gifts I made for my dad. They kinda go together but I think I gave them to him on two different occasions. The top one is a stair saw. You can barely see the teeth on the bottom. It is a small saw with an adjustable blade depth and it is used to delineate a dado in a piece of wood. Hummm, that was kinda obvious as I don't see someone trying to cut metal with that!The black spot on it is a quarter that has been coated with titanium/aluminum nitride! I used to work with a high vacuum plasma coating machine and I'd throw my spare change in it just to see the results. Anyway, the quarter has the correct year that I built the saw on it.
The bottom one is a router plane. It's kinda nice, you can see I've made progress in the design of handtools if you compare this one with the one I won the contest with. They go together because you would then use the router plane to remove the extra material in the dado you delineated with the stair saw.
