Hello,
Grind and edge geometry does come into account on the total overall knife, but without a proper heat treatment and proper
thermal tempering cycles ,why bother?
I think a "HARD USE" blade is one where you the user Subject it to such use, the question then becomes can this knife do the task i put before it. I think its kind of a mis-interpetation to Lable a Knife a "HARD USE " knife, when any knife can become such an animal if called upon to do "HARD USE" work.
I have made Survival Emergency shelters with a 4-inch Drop point hunter, testing this blade to see if it would take it, sure it did, and it was hammered on with Clubs to split poles, Used as a boring device, and to make field expediant weapons out of the natural Fauna. So i guess at those moments in time it was a "HEAVY USE" knife, Although it required more Actual use to accomplish the tasks than say a larger blade would have required it still performed to the Level of the Big blade by still completing the task`s.
but like i mentioned, in my opinion if you have a blade to soft for its specific alloy,
or if you have a blade that is to hard for its alloy,,,,there is no way you will get complete total Performance levels out of it no matter if it is, hollow ground, flat ground, thick ,thin, ats-34, 5160,D2, 1095 or whatever else you can put in the mix.
Whithout the proper Heat treat you might as well Plan on spending alot of time being disapointed.
My opinion only
