    For anyone watching this: It's better to start with the lower hardness files and work your way up. That way you don't have to make so many marks in the piece.
    Look at the chromoly piece, he had to make six sets of marks in it just to determine that it's so soft it doesn't even register with this file set. If he'd have started with the 40 he would have only had to make one mark.
    Same with the carbon steel, he put 4 sets of marks in it working down from 65. If he'd started at the low end, the 40 and 45 wouldn't have made any marks at all, then when the 50 bit he'd know it was between 45 and 50 *and* leave only one mark in the piece.

      No. That's not correct. Tool guy did it properly. Starting with the lowest rated file and working up could ruin your files. To preserve them, you must work from the hardest, to the softest.

    Very good. Just bought a set of files. Most of the knife blades I buy to put handles on them are not close to hardness there claimed as
