My Leatherman Wave tool is 97% wonderful, and the other 3% of the time I want to throw it into a lake. Keeping it SHARP is one of those times the lake and the tool are close to meeting. I like sharp knives. Really, really sharp knives. I'm perfectly aware that there's a compromise between versatility and the ability to hold an edge, but I really am quite unhappy with the ability of the leatherman to take and keep a sharp edge. Has anyone else encountered this? Any ideas how to cope?
