I've only used one knife, an EZ Lap diamond rod and a home made gambrel. I used a Western Cutlery sheath knife with a 5 inch blade for many years until it was stolen. I bought a Finnish Lauri blade with differential temper and made a nice handle for it. The thing is like a straight razor! The cutting edge is only 3 1/2" but thats fine. I do much like everyone else here as far as skinning and gutting. The gambrel lets me pull the deer up to stand up working height. I'm 67 and have a busted lower back so that is a necessity. I hook the gambrel to the deer's legs at the knee's, tie a rope to it and hoist it up on a limb with the pickup truck. That works for me.
