    Hardness vs Wear Resistance? BladeForums

    Jan 20, 2011· Increased hardness has a much larger impact on lack of edge deformation than on wear resistance. IMO edge retention is a combination of wear resistance and an edge that does not deform. If you compare the edge retention of two blades of the same alloy, one at ~56 and one at ~58, the blade hardened to a 58 will have better edge retention.
