The KA-BAR is a combat knife that is used by Armed Forces World-wide. It got it's name when a trapper sent a letter to the company that made it about how, after his gun misfired, used it to kill an attacking bear. But the letter was so hard to make out that all that could made out was "K a Bar"-to kill a bear. It was the most popular combat knife in Vietnam, and continues to be used to this very date. It is great for stabbing, slashing, searching for mines, cutting rope, and other useful things like that.
