>>2383606Here's a graph of high carbon steels in their optimal hardness/ toughness ranges. More or less hardness will reduce toughness interestingly enough.
Do you know what steels your blades are? All of what I'm saying is more specifically for high carbon steel. I would guess some outdoor knives maybe be in the medium, medium high carbon level, which would greatly increase toughness at the sacrifice of hardness.
