Perhaps that is why Big Green issues a multitool instead of a KaBar nowadays?
That might also have something to do with all the city boys who have never used a knife for much more than spreading their peanut butter and jelly, or maybe cutting a steak, if Mommy doesn't do it for them. They only know hack, slash, and stab. Everything they need in a video game. REAL sharp tools would be dangerous. And expensive, medically speaking.
There's also the number of hard cases that are in the military to avoid going to jail. They're the ones who already know knives as a weapon. Better to not give them a tool that's actually quick to get into service! This could also be expensive, medically speaking.
In both cases, a serious lack of impulse control is going to be a common trait. One side doesn't know the consequences, the other side doesn't care. The end result is the same.
And it's really not anything new, or even different. Navies have been giving sailors knives without points for centuries....
