I have and have had a lot of knives. None really fancy or anything, but I do like some of those sponsor knives. Maybe I will treat myself to one.
I used to always carry a mid size fixed blade belt knife. Now for the last dozen or so years I find I always have a Browing Kodiak F.D.T. 3-Blade on the belt. It has a drop-point blade, saw and unique hide-cutter blade which can be used as a standard gut blade when pushed or as a guthook when pulled. IT has a Zytel handle. It really seems to hold a edge well. All three blades lock, and the saw blade is replaceable. The saw blade is really a fast cutter with a double row of teeth unlike any other saw blade I have seen. It cuts through stuff much faster than other folding saw I have had even at its small size.
