My father-in-law passed away four or five years ago. He was an engineer, as was his father. They were great accumulators of tools and I received a lot of them when the house was cleaned out. There were some very ancient tools in the lot, things like tiny drawknives, woodwork planes with wooden bodies, very curious folding rulers and a positively wonderful one-man crosscut saw (as well as two chainsaws). There were lots and lots of chisels, rasps, files, drill bits and I don't know what all. I got it all cleaned up (they lived near the water and rust was on lots of it) but have used very little of it since.
I remember walking around with him a year of so before he died. He said he didn't want "us boys" (there was a son, three son-in-laws, and a number of grandsons) to fight over any of his stuff. But there was enough for everyone to have all they wanted with plenty left over that was given away. So I wound up with a lot of stuff I didn't need. To be honest, I went down there with the idea of not really taking much but when it was there in front of us, some of it looked mighty interesting. One of his tool boxes was marked on top in red paint "Damn metric tools." That tells you a lot about my father-in-law, who by the way, was in the Army Air Corps in England in 1944-1945 in a bomber unit.
