My taste in knives has changed a great deal in some ways, remained chiseled in stone in others.
My taste in knives changed most about size. I used to be a medium size stockman and SAK fan. The Buck 301 and Wenger SI/Victorinox pioneer were my go-to knives. After my dad passed away, I started to carry his old Case peanut just for sentiment. Then one day is actually used it to cut something. Then I used it some more. Then I had a light bulb moment as to why dad always carried that little knife. I went an bought one of my own.
I found out that for my life style and most things in modern American suburbia, that little thin blade a bit over 2 inches was enough to cut most of what I needed to cut. But the gain was a very small package that dropped down to the bottom of my pocket and was actually forgotten about until I needed a knife. It started me experiments in small pocket knives and how much I could do with a 2 inch blade. My stockman and larger SAK got put away and I went to very small pocket knives. Buck 309 companion, Boker 240 penknife, Christy knife, a small Buck Hartsook fixed blade. A Victorinox executive was added in and took over my watch pocket of my jeans or the pocket of my Magellan fishing shorts that are my go-to shirt in Texas summers. . I never carry any pocket knife that won't fit comfortably in the watch/coin pocket of my jeans. If I need more knife, I'll carry a fixed blade like my Buck 102 woodsman or Martini puuko.
But my taste for multi bladed pocket knives has remained the same. I never got into the single blade lockers, just too limited with just that one blade. And I still love a nice thin blade. I found out the thin blade a little Victorinox classic is like a razor blade when sharpened up good. A little pocket scalpel. Likewise the small blade of a Boker 240 or Christy knife.
But the real change is how much my obsession with knives has changed. I stopped collecting/accumulating, and sold off/gave away most of my collection. Kept a small handful of the smaller traditional's and I don't really care as much about knives as I used to. As I got older, it became much more important to me to go out an live life with those that I loved than what knife was in my pocket that day. Doing things with my wife of almost 50 years and the kids and grandkids became what mattered to me. As long as I have some kind of small sharp knife in my pocket to trim fishing line, open packages, or whatever, I'm good to go.
Doesn't have to be big, just sharp. A wise man once told me that.
