Well, in terms of actual victims of being slashed in combat, the average infantryman would offer the lowly entrenching tool as the most deadly edged weapon. An E-tool you have, the niceties of a mess kit, rare.
If you are enjoying the luxury of hot food with cooks, you are in a rear area. That means logisitics, and utensils, plates, and cups readily available. It's a lot more sanitary and less problematic than dunking utensils en masse and pretending they are clean and nobody will share whatever gave them the heaves.
As for having them in a soldier's possession simply because they were issue - not much in my experience. Supply sergeants like to have things accountable, and equipment floating around for no use doesn't help them feel secure. Neither for the final hand receipt holder, his supervisor, or the Commander who has to answer for every cup, spoon, and lug nut. He's the one who gets the final bill at the change of command inventory.
Nope, my votes on the e-tool. Bayonets are kept locked up, mess kits are too pilferable, but if you're in the field, whether friend or foe, the e-tool can straighten out some attitude, edged or flat.
