And last but not least...ZDP-189. Kershaw is the only manufacturer allowed to heat treat their own ZDP outside of Hitachi's facilities.
I know I've missed a few. And out of the list above...how many of those was a "first to market" by Kershaw?
Feel free to give me a comparative list from Spyderco...I know they've done some options Kershaw has not...O-1, M-4...
Not saying this list is inaccurate, but when did Kershaw use s90v? I missed that model. Regards, Steve
