I bought two, I made this one up for
@TheViking but haven't sharpened it yet. I'll do that tomorrow and let you know.
I do drill those small holes to 1/4" using a $50 fancy carbide bit. From how the bit responds I have a good idea of how the steel will sharpen. For example, with Zmax I had the steel chip out twice on the backside. PD1, Zwear, Magnacut, all drilled out easy with no heat. Rex76, M398, pma11, s90v all drill fine but produce heat. Those last four also sharpen up smoothly at the correct angle with the two stainless being lightly more finicky. I don't forsee any problem sharpening but I also haven't checked the Spyderco forum for any feedback from others yet. I do think it's a steel that should stay away from joints.
@Ucsdryder has the only Rex76 I have finished up yet (of the four I bought), and his s90v ridge knife. he can let you know his opinion of what I think is sharp.
