I still have my old Swiss army knife I got when I was eleven and in the Boy Scouts. It’s 30 years old, both blades are still sharp, though those edges have been dressed, and the only thing I lost from it was the toothpick, but the tweezers I still have.
I too have one from decades ago. I saw a little knife shop during a vacation a few years back and found a replacement toothpick.
I am not a collector but I have probably over a hundred pocket knives. For many years I carried a Puma Stockman. It is very high quality but I no longer carry one.
Back in the early 60s I read an article in one of the sports magazines such as “Outdoor Life” about knives. The author made a comment about Swiss Army knives. He said he thought tools belonged in the tool box not on a knife.
I thought this was really clever and for years would not even consider carrying one. Then I actually used one and decided that guy didn’t have a clue. I usually carry a super tinker or one of several which have the toothpick and tweezers.
The things I use most are the scissors, the tooth pick and flat bladed screw driver. Maybe the knife blade is next then the Phillips head. I prefer the Victorinox over the Wenger but not by a lot.
