I dunno about this argument. The military gets issued gear from the lowest bidder. They don't get issued the "best." Plus, people can make the worst tool work if they're motivated enough. Adequate doesn't equal good IMO.
I don't care for the Kabar. As a fighting knife sure but for utility the tip is too fragile and like has been said before the tang is poorly designed. Fix the stress riser issue in the tang and do a less aggressive clip and it would be worlds better and cost just as much.
Its all relative I think. I say a million Marines can't be wrong, because the Kabar hasn't been an issued knife in a very long time, yet, it is still the most sold knife in Kabars lineup. They are found in every PX/BX across the globe, and military men and women are paying for them out of their own pocket.
Talk about a knife with a reverence, ask any Marine, from 18 to 80 what knife they want on their side, I'm betting I know what the answer will be. And its not just the Marines, I got few buds in green that will give.you the same answer.
Does that mean it is the be all, end all knife? Hell no, no such critter exists, but for an easy to buy, easy to use, tough enough to be abused, and so affordable that a private can get one, there aren't many out there that can come close.
Does it have flaws? I don't see it that way, what I see is a design creeping up on a hundred years of being a viable, and actively made knife with a rich history. It works, or it wouldn't have made it this far, if it sucked.
The only changes made to the design, is a step up in modern metallilurgical processing, to render a tougher blade, with better edge retention.
