I used to have to re-grip during use by sliding my hand back up towards the choil every once in a while. As far as an o-ring, you could try it. The fusions are the best feeling in the hand for me and I've owned them all. Including the zero tolerannce line, Ergos, straight, and fusion. That said, I like the look of the SHBM's the best. If I ever get another one I will round out the radiuses around the rear talon as papathud mentioned. And I would do an extreme job of it. really smoothing out those edges. Man that would be nice. The only thing about the older SHBM's is the fact that my slotted 1 of 300 was about 1/8" shorter than the others and 1/4" thinner (from edge to spine) Looked like someone had screwed up the bevel somehow and tried to grind a lot off the edge area to get it normal again. It was also wavy at the edge. On a DMT it was very obvious as several portions of the blade didn't contact the stone until a very extesive several hour reprofiling process. They have come a LONG way. -Jeff
