To put my response in perspective, I thought it would be meaningful to tell you what brands my knife universe consists of.
I have been gathering knives since I was a kid. Currently I have a number of Benchmades, Cold Steel, Gerber military knives, a Buck folding hunter, a Polkowski Bodyguard, and other assorted odds and ends. Without any doubt, my Cold Steel XL Voyager plain edge tanto, San Mai III Master Tanto, and Urban Skinner were sharpest out of the box and take the best edge. The nesxt closest would be the Buck folder.
