I don’t know the model number but it’s the Buck Personal I bought new in 1978 after struggling to dress my first buck with a cheap knife. 4” blade, gets and stays sharp even through the uses I’ve put it through, including opening cans and cutting wire in a pinch. It fell off when my belt came unbuckled dragging a deer outta a swamp years ago and I walked back a mile to search for it, and woulda been crushed if I’d lost it. The 4” blade has been great for countless deer, also bear, caribou, small game and even fish when called upon. I love it and know exactly where it is, always.
