  • Hardness vs Wear Resistance? | BladeForums.com

    Jan 20, 2011· Hardness I see as more resistant to impact while I view wear resistance as how difficult it is to grind away. A increase in hardness will bring more wear resistance but its not the same as adding large amounts of hard carbides to increase what I guess you could call its "standing" wear resistance.
