I have carried a knife daily, since I was nine years old, I use it almost daily. Buck, Kershaw, and others make good quality knives, but no one tempers their blades as well as Benchmade. Using S30V, 154CM, or another good steel, Benchmade's edge will outlast the others, and their quality is usually better. I have Buck, Kershaw, Gerber, Boker, and other makes of knives, but I carry a Benchmade. A good knife can prevent someone, who gets close enough, from taking away your gun, it is a good idea to carry one.
