I carry a knife everyday, sometimes more than one for different reasons. When I am hunting, I carry two in my bag. I have a Benchmade fixed blade infidel upside down on my pack strap in case I ever need it. It is one tool when, if you need it, you need it and there aren't many other substitutes. I probably over pack my bag which weighs in at 42 pounds but you know what? If I had to spend a few days in the bush if I was hurt or lost or sick, I would be confident and comfortable doing it. Between my emergency kit, first aid kit and survival items, a good knife is a must have when you venture out. I have a Leatherman Wave in each of my quads, one in my snowmobile and pickup, one in my backpack and usually carry one on my belt. Be prepared.
