Currently in the running for the #1 spot. Although, I'd gladly own any one of them if I could either find or afford them.
Hoback A10 or really anything by him.
Stan Wilson custom.
Hinderer XM-18 Aggressor Grind.
Jeremy Marsh "chipped titanium" Vanquish.
Microtech Nemesis IV.
Tuff Tanic custom.
Direware Solo, non-recurve.
Shirogorov Hati.
Brian Tighe custom.
Granted, it's really hard to say without having handled them. Hopefully I'll attend BladeShow at some point and get some of them in my hands.
Edit: Man, I have a problem. I honestly don't know if I could ever justify having well over 20 grand in knives. Well, it's nice to dream.
