It's been quite a while, so you may not be reading this, but the handle isn't that bad. You could possibly get a pro to round off the corners a little, but I don't think it would make too much of a difference. The shape, although a bit blocky, isn't that uncomfortable, and stops it from rolling in your hand.
I had thought about getting the clip sharpened, but, I don't think that, on the tiny chance I ever did have to use it in self-defense, I would ever need to do a back cut. Besides, people don't really get into knife fights anymore. There are knife attacks, though, and those happen by surprise. If I did need to use this, it would likely be against an ambush when I'm in the woods, and only then if I could manage to get it out of the sheath.
