The KaBar was a low bid answer during WW2 to the need for a non-strategic materials made 'Utility Knife', meant for depalleting supplies, opening crates, and, yes, personal defense. No hi-tech materials, like SS and rubber as they were needed in the aircraft industry. Just 1095 carbon steel, leather, and brass/copper rivets. I inherited my Dad's old KaBar in the sixties - took it camping and even off to college in '66. My Dad carried it, a USN version, in the South Pacific during WW2 while in the USCG and stationed on troop ships. One thing it was of no use in defense from were the Japaneese torpedoes.
I was a USN ET from '69 thru '72 - and seldom carried even a SAK. Camping saw that KaBar with me - until I dropped it on my concrete workshop floor in the eighties - and the pommel broke off at the reduced tang - eventually to be refitted with a monel pommel, some 'weathered' new leather washers, and... JB Weld! Still serviceable, I just wish I had preserved it. KaBars are still available new - don't do as I did and damage one that has some history- just buy a new one to use as a 'user'. I've found commemorative models for as low as $30! Here is a recent production, my Dad's old one as it is today, and a Bark River Boone - obviously, like so many other modern models, it owes much to the KaBar's timeless Bowie interpretation. My Dad's old KaBar never had the secondary bevel of the new ones. Still useful piece of history.
I trust everyone had a Merry Christmas - and will have a safe New Year!

PS I almost forgot! A KaBar to fell a 30" tree? Mighty ambitious! I used mine to chop firewood when camping - but I quickly learned the utility of a Plumb 'camp hatchet' in that endeavor. It was relegated to making walking sticks and even attempts at a flute - too much knife. One day I realized I had a Buck 110 with me - and a SAK - and never toted the KaBar in the woods again. Nowadays - with a myriad of choices - my woods treks involve my wooded backyard. Time!
