The best? The very best?!? You are killing me here asking me to pick ONE but I'll do it.

Up until last week I can easily say that it was my Camp Tramp in Tan Res-C with a custom DC finish. But then I received my ASH1 LE in the mail... <img src="/ubbthreads/images/graemlins/ooo.gif" alt="" /> The ASH1 LE feels perfect in my hand and has tremendous balance. Also, INFI is tougher than nails and corrosion resistant. Ask me again in a week, but I think if I had to pick just one, the Tramp has been bumped to #2 with the Ratweiler and S6 close behind.

If I have the luxury of adding to my main knife here's my current picks:
Pocket - Strider SNG, tough and easy to have with you all the time
Necker - Rat Warden, a great backup slicer
Big'un - Dogfather LE, for heavy splitting/batoning

Give me that setup and I'm more than happy.
