I've known two persons that did the stabby-cutty thing for living.
The colonel in the Israeli paratroopers was fond of her Fairbairn-Sykes. She had a lot of practice with it on sleeping Syrians.
John, my buddy who went through the Bulge was particularly keen on a Ka-Bar. He used it on everything when we camped. He said it worked equally well batoning through sheet roofing or finishing off the odd Kraut.
At the time, I was carrying an Air Force Survival Knife as a general-purpose blade. I generally kept it concealed at the top of my rucksack so I could reach behind with either hand and retrieve it. Neither one poo-pooed my choice.
