I joined that club about the time I got into my 50's.
For 25 years I carried a Buck 301 stockman as my everyday pocket knife. There were some 91mm SAK's that came and went, but that was the smallest. Then I gradually downsized to a Buck 303 cadet. I was happy there. I had a Stanley utility knife on my workbench t the job, and if I went camping or hiking Ihad a sheath knife on the hip.
One day a few years after my dad passed away, his old Case peanut was sitting in the try of stuff on top of my dresser, and on whim I dropped it in my pocket and took it to work. My dad was a study in minimalism, and he always carried that little peanut as his go-to everyday pocketknife. He had a cut down machete in the trunk of his car for the bigger stuff, and the peanut handled everything else. Well, I tried it.
I ended up buying a peanut because I liked having more room in the pocket and a knife that weighed very little and did what had to be done, knife wise. I tried an experiment; for a month or so, I deliberately left my Buck stockman hem and just carried the peanut. I never went back. To this day, I carry a little Remington peanut as my edc pocket knife. I have kitchen knives in the kitchen, a machete in the car trunk, and a sheath knife in my hiking bag. The peanut does 98% of my cutting.
Then my better half got me into the Victorinox classic. But that's another story.
So, yes, my knives got a great deal smaller as I got older, and a bit smarter and took a long hard look at who I was, and what I was. As a retired gentleman of leisure I don't really need more than an inch and a half to two inches of blade.
These are my go-to blades these days. All are under 2 inches and do all I need in a urban/suburban environment.
If they won't do it, then it's time for me to use my dad's old bushwhacker in the trunk.
