20+ years ago when my son was little, my ex-girlfriend and I took him to Boston to walk the Freedom Trail. We got to the USS Constitution and they had TSA level screening and found my Victorinox Swiss Army knife and said I couldn't take it in and they couldn't hold it for me. It was either dump it in their drop box or don't go onboard. I had had the knife for about 30 years at the time and my GF knew it was sentimental to me and so she volunteered to stay back and hold it for me while my son and I went on the ship. I thought she'd want to go on when we got back but she was good calling it a day. I still carry the knife daily, so I've now had it over 50 years. The big blade has been repeatedly sharpened down to half its original size, the red scales popped off a few times and were glued back on, the corkscrew wobbles due to a weak spring, and the lanyard ring anchor wore through years ago and the ring is long gone.
It brings back memories of fishing with my dad - we were at a lake up in the mountains west of Boulder CO when I was 12 and if they weren't biting I often spent more time exploring than fishing. While roaming the shoreline, I found an old windbreaker that someone forgot and this knife was in the pocket of that jacket. It seemed to be in like new condition back then, and probably was. Up until then, I'd lost every pocketknife I got, but somehow managed to keep track of this one. Somewhere there is a picture taken that day by my dad of me posing with my trophy 3" perch and another one I took of dad holding a similar fish - which was all we caught, but the memories are priceless.
A couple weeks ago, a friend brought me a S&W model 28 that he needed shipped and it had Pachmayr grips on it that covered up the SN. So I whipped out my pocketknife and pulled out the combo bottle opener/screwdriver blade and he chuckled, pulling out his own knife which was the exact same model. I think it was called the Camper. Large/small knife blades, bottle opener/large screwdriver, can opener/small screwdriver, and the back side has a corkscrew (instead of a Phillips), and awl. No toothpick or tweezers. His was "only" about 20 years old and in much nicer condition than my 50+ year old example.
