My favorite is probably the one in the stump with the leather handle. I really like that one.
And it is sad to think that my math was calculus and my science was all the advanced courses, but none of that matters a whit now. I would love to have had math as machining and science as metallurgy. It would have been worlds more useful.
I didn't know how it would all work out, but it has shown up throughout my life. I learned a great deal about being able to see something and then make it. I can't wait to see what is next!
