Venice, I think its a matter of perception. As a fellow old fart, and being retired with lots of time on my hands, I'm actually using a knife more now than when I was working. When you were a kid, did you ever wonder why all those old guys we'd see all used a little pen knife that fit in the 5th pocket of the jeans?
They knew what it took me to be old to figure out; it was all that was needed 99% of the time. Being retired, I have almost unlimited time for fishing, woods walking with the wife and dog, tinkering with home projects, and opening all those packages that I used to be able to tear open before I got old and had arthritis in my hands. A sharp edge is now mandatory equipment for this old fart. Making a nice clean cut to get things started is a good thing.
But...how much blade is really needed for opening mail, Amazon packages, plastic blister packages that are designed to withstand small charges of C4?
What changed as we aged is our outlook. Perspective. With the passing of many years, maybe the testosterone levels drop, and we're not as influenced by the fantasy of being marooned in the Alaskan bush, or blazing thought the Amazon jungle, or even taking out sentries with our wonder knife of the month. How much knife do we need to trim some monofilament fishing line, or zip open a package, or cut some jute twine to tie up the tomato and pepper plants out back?
With senior citizen age, there sometimes comes a new pragmatic view of whats left of our life and what we need to deal with that. Theres not a day goes by the I don't use my knife for something several times a day. Yet it all is able to be cut with a SAK classic, Christy knife, Boker 240 penknife.
