Many of my knives have a story but nothing like the stories you all have. I dont have my dads or grandfathers, as far as I know neither actually carried a pocket knife. Grandpap was a steel roller supervisor at U.S.Steel in Pittsburgh,, Dad was an officer in the O.S.I. his EDC was S&W model 36.
The three I would consider sentimental are knives that have been with me a long time, the first was my Ulster Boy Scout knife, given to me by my father in 1960, though he wasnt there that Christmas, he was stationed in Greenland. I carried this knife for years, on two continents many states until I was in High School. I thought it was lost, after my father died in 1983 it was found in his jewelry box, Mom gave it back to me.
The long hunter was the first knife I made and I keep it for the lessons the making of it taught me. I learned why custom made knifes aint cheap and gained much respect for bladesmiths. It was made around 1988.
The Victorinox is an early version of the Climber, I think, no mystery hook. I bought this knife around 1975 and carried it up to 4 maybe 5 years ago. I put the bone slabs on it in the late 80s. After carrying it for near 30 years I got to where I was getting distressed when ever I misplaced it, usually it fell out of my pocked while driving the Toyota. I decided that it was silly to stress over a $20.00 knife and retired it.
