To mention a few more:
Rick Hinderer - He just came up with a few new models for 2014 with some interesting blade shapes and grinds. A lot of his knives are "mid-tech", but he also does some full customs.
GTC Knives- Always something different and interesting blade grinds
Curtiss Knives - Bomb Proof Knives that are smooth opening.
Calavera Cutlery (Jeremy Robertson)
G & G Hawk Knives (Grant and Gavin Hawk)
S.K. Knives (Steve Kelly)
WDZ Knives (Zermeno Knives)
Hope this can give you some other options... Take Good Care, Good Luck, and Be Safe Always.
