Thanks man,paper micarta or canvas micarta?
Canvas Micarta can be rough or can be polished, obviously we are talking about the rough type. I seem to remember that it can be bead blasted to make it rough.
It also seems that rough stacked leather handles would be good. I've seen stacked leather that was sanded smooth and lacquered but I've also seen stacked leather with no finish on it and where the stacked disks were of various diameters so the surface was rough and irregular. I think one of those would be pretty good for traction.
