    Oh I know. :D

    Have to finish that one up with the rest of the testing and then start on the Caribbean Serrated.

    Thank you, Jim and gine! I was expecting a high hardness, and it agrees with what Sal told us they were getting on the Military model.

    I wonder what the smaller PM2 and Para 3 are Rockwelling at.

    I have a Bull Shamwari in Twist Damasteel and it's one of the few hollow grinds that doesn't have that "bulge" you're talking about. Helps that it's ground uber thin, 6-8 thou for most of the edge with a thicker tip. The crazy thing is how thin it stays past the edge. It takes 5-6mm to pass 10 thou on the primary grind, never seen a hollow grind like that. I have a few Krein regrinds(Elmax para 2 and zt 770) that are at 5 thou but being FFG they thicken up rather quickly. Certainly wish more companies and makers made knives better suited to cutting. Microtech seems to have rather lean grinds(at least the 6 I've had were) and most South African makers stay in 10-20 thou range(Thorburn, Van Heerden and CPK from the ones I've seen) . You can have the best steel but if the knife geometry sucks it won't cut worth a dang.

    Bump

    This thread should be a sticky. I don't understand why it isn't.

    Thanks, a lot of people have been asking for it for YEARS and it hasn't happened yet.

    @Ankerson

    You have Vg-1 listed two categories above VG-10

    But I only saw cut results for the VG10??

    So did you confirm the actual HRC value independently for this test? Apologies if I missed this.
