So I was meandering around a local flea market this weekend and an old fella had a tool box full of old Nicholson Black Diamond files for super cheap so I bought all of them. Now I know a lot of people think that files aren't an ideal knife material, but for what I've got in them, I'd like to try them out. From what I understand, the run of the mill Nicholson files are 1095. However, after researching as best I can, I've seen in a couple forums that the Black Diamonds can have as much as 1.25 carbon content? If this is so, how would I go about getting the correct heat treat/hardness? Could I simply temper them down and work them as is carefully without getting them too hot and skip the heat treat? If so, what's the process for doing that? Thanks for the help guys.
