Slider, I use to carry every tool I could think of "just in case" I needed it. As I get older pack weight is more important. On day hunts for field dressing I have settled for "two" high quality non-folding knifes, Allen saw (mostly for knobbing the knees of deer to drag easier). Elk hunting I add a sharp ax and game bags.
Other gear include flashlights (I have many mini-mags and a LED light, LED hat light in my pack), drag harness, parashoot cord, survey tape, first aid kit, zip ties, leatherman multi tool, three or four lighters in different pockets inside ziplock baggies, emergency fire starter, a couple glow sticks (emergency use), extra "D" rings (make good pulleys for hanging meat). GPS, range finder, two way radio,lots of water, food.
