Funny, the things you think you will use a knife for in war, are rarely accurate. I took a KA-BAR USMC and a leatherman wave to Iraq... and about a half dozen others, but those are the only two that made it home. the rest were traded away for British rations. both were well used. the ka-bar built furniture, showers, etc, as we didn't have a hammer (2003). nobody I knew ever used a knife as a weapon, but that's not to say they weren't infinitely useful. Also depends on the theatre. In a jungle/woodland, I'd go with an ESEE 6, as I don't like the KA-BAR for bushcraft, but I'd still keep the multi tool, probably my SOG. and a SAK, I will never be without one.
