i tried something new on a recent finish by taking some buffalo leather and wrapping it inside out on the handle, then lightly misting it with water and gently heating it with an iron, this caused it to shrink tight as well as brought the grain of the leather up, making it grippy(kinda like the rough leather work gloves). it turned out pretty well. one thing is that if you get one spot more than another it causes the color to be darker/lighter so maybe spray/iron once before you put it on then do it after its on just to get it to form. oh and im sure you know not to hold the iron in one spot long.lol. it dont take alot of heat to do.
