Shaman’s are one of my favorite knifes to mod, as it really transforms the look and feel of the knife. I can’t stand using one without a nub delete now. The crowned spine gives a much nicer feel on the jimping and top of the blade similar to CRK knives. I do this on wet diamond grinding wheels so it won’t affect the heat treat of the blade.
I crown the spine and jimping and deleted and polished the nub as seen in the video here: Spyderco Shaman
