Also consider the Air Force Survival Knife. The good thing about this knife and the USMC KA-BAR is that they are a well proven design, and standard government issue to the military. You can pick them up at very good prices.
Sure, you may want something special, but until you know what that something special is, pick up a classic military design for a good price. With a classic military knife on your belt, then ponder how it could be refined or improved for your uses. Or just use it, as I did.
When I was in the army, some carried Bucks, some KA-BARS, some Air Force survival knives, some trench knives, some Cold Steel Tanto, some exotic this or that. It didn't make much of a difference at the end of the day. Just get a good strong fixed blade knife and carry it. Oh .. and a Leatherman / Gerber multi-tool too, carry both.
Now Crack-On with your job, as my Sergeant use to say.
