An old buddy who had spent a good many years in the U.S. Navy told me all he ever needed to work his way out of countless bar brawls in ports all over the world was just a small 2 blade Case jackknife, and even then he said he only used no more than a 1/2" of a blade tip.
He said, "All you gotta do is just show them their own blood and they move out of your way REAL quick".
