I'm a little bias because 52100 is one of my favorite steels, really its hard not to like because it performs so well. It can chip if the edge is thin and you hit something hard like a rock but I've only had that happen once and I was trying to make it happen. Most of the time its nothing more than a small roll or deformation.
I don't think its real shock resistant though, beating it with a wood baton ok, pounding on it with a hammer not so much.
