This thread is a must read.
Pierre, you've taught me boat loads about HT, and your post really rounded out Marko's initial one. Combined (with Jon's comments, of course), we have a very good summary of how intricate and individual ht can be. Basically, what it seems to boil down to is: there are fantastic "mixes" or "cocktails" that are used. If you want more wear resistance, or sharpness, or whathaveyou, it's a good idea to use a knife or maker that/who is known for the qualities you desire.
