Are you really saying that it's good to give combat troops a poor combat knife because they might use the knife on themselves? Maybe we should give them rubber bullets, too.
There are no combat knives, just utility knives issued to combat soldiers, especially since the invention and perfection of reliable firearms. Many Naval services have required blunt tips for centuries because some sailors settle arguements physically - and the hazard of using a sharp point on a rolling vessel.
IIRC the last combat "knives" issued were the Ames short sword in the 1800's, or sabres to a Brit Cavalry unit in the 30's. Even the SEALS aren't issued combat knives, they're issued Dive knives for utility work, which is the primary purpose.
If the BM auto with a NSN for Coast Guard issue is a combat knife, I have serious reservations about the design. As a fun to use but never carry folder, I like mine just fine.
As for troops using a knife as a weapon, most likely in the barracks, almost never on the battlefield, which is the bubble bursting reality that colors a serviceman's impression of advertising.
I got rubber bullet training in GTMO, and it does have a place in non-lethal weapons escalation of force scenarios - riot control. The rubber claymores are even more fun, along with the rubber shotgun rounds.
I don't know why a Italian artillery spotter unit would need them anymore than some fantasy commando knife to cut brush for camoflage and firewood. I do understand the reality of humping 60 pounds of basic load up six flights of stairs - these guys look like they get to do that repeatedly all day long in the hills, so forget axes and hatchets.
The RAO just makes more sense the more I think about it, but I'm obviously not as well informed as others.
