I am not a big fan of the tdi series of knives. I have one but I never use it. It feels akward in my hands. I tried using it to cut some materials and the angle it creates actually causes whatever it is your cutting to hit your hand. I just didnt like it.
Knives of Alaska makes a great 100% made in america knife. I actually use alot of there knives for hunting (skinning, gut hook, etc). I am hoping to get a new set for my birthday from the wife this year.
