I did not get to do any toughness testing or anything of that sort But I did get to test the edge holding on a bunch of cardboard before I put the final finish on it. It just kept going....and going....and......well lets just say it holds a pretty darn good edge. I have heard of others using M4 even at 65-66rc for skinning/hunting knives. I would think that toughness is not that ideal at such hardness. Hopefully, the end users will have the common sense to know what they have and that some toughness will be given up to gain wear resistance. Most super high wear resistant steels are not that tough when compared to the likes of A2, S7, 3V, and other less alloyed steels. But CPM-M4 is still relatively tough for what you are getting in wear resistance.
