I have a custom made knife that was given to my dad back in the '60s. Blade is made out of a file. So hard and heat treated so properly, it rings when you hit the spine with a screwdriver blade.

You probably also tempered it enough that it doesn't break. A file is quite brittle, I vividly remember
slamming one down on a wooden workbench when I was about 15 years old and it shattered into about
gazillion pieces. I used to have quite a bad temper but learned to control it.

When I say tempered the steel you're actually stabilizing and softening it enough to not be so brittle. So many
times I hear people say, "don't get a hardened piece of steel too hot you'll take the temper out" when you're
actually putting temper into it. Took two quarters of Metallurgy at Tech. over 30 years ago. Have done
case-hardening, oil hardening, water hardening and air hardening in which we would seal a piece of air
hardening steel in stainless steel foil before going into the furnace so the that the carbon in a piece of A2
steel doesn't get lost in the heating process, if I remember that correctly.
