Doh! I didn't think about the magnet. A small screw driver on my key ring is magnetized and gets used for that.
A person I used to work with/for was a blacksmith and had a small assortment of things he always carried with him for testing and inspecting things he found. Some of my hunting habits were learned from him.
I think Sargent planes had the "Bedrock" set up before it was adopted by Stanley. Not sure of this. As I have said before, many users feel Sargent built a better plane. In my opinion, the Union plane I owned was slightly better than the Stanley planes of the same size. Stanley planes are good planes, others are undoubtably better. In the end, it is what they can do for the person using them.
