If a custom knife is made one at a time by hand (perchance with some help from power tools) then I don't have any customs. On the other hand, if you take the word "custom" in the loosest sense (any knife not make in a big knife factory), then I have a number of them from Chris Reeve, Newt Livesay, and Bob Dozier. Of these, I don't hesitate to use the Livesay's and the Reeve's everywhere. They are true "tactical knives" which I take to mean built rugged, intended for use, and maybe even a little abuse. My Dozier (his "Master Hunter" from A.G. Russel) is another story though... That knife is so specialized, and so sharp, that I carry and use it for only one job, skinning. I always make sure I have something else (usually my CRK or Livesay) for all those other jobs a knife has to do around a camp.
