Classic knife. Do you feel the Kabar was purpose-built for fighting or for utility? All I keep coming up with when I think "purpose-built for fighting" is stuff like the FS dagger and 1917 trench knife....worthless for everything other than sticking people.
I think it was the first knife to straddle the line between fighting and utility. The blade shape works for penetration, a strong center line clip, 7" in length to get to the vital innards, and double guard. Because, lets face it, when you get to the combat side of edged weapons, stabs are really the best. Bayonets, rapiers, etc.
I think the utility comes out in the straight blade, easy to cut/carve/chop vegetation for cover, clearing, or camouflage. As well as the flat pommel for pounding stuff, yeah, I know its not the best, but it does work well. And then, the blade width worked well for prying open ammo crates. Not being used like a pry bar, but driving them in point first, the rotating the blade. I'm betting they used them as pry bars too, but the only records I have run across, show the "twist" method being used more often.
Imagine opening an ammo crate with a 1914 or Fairbairn/Sykes.
I like it, its got quite a few features that show off its strong and softer sides. In camp or in combat, its the fashion accessory no Marine would be without.
