I think you find a lot of the old knives still in stock in small hardware stores simply because they have no demand. Even the contractors who really work for a living don't use them.
Careful... this one does. If I leave the house and DON'T have a folder in my pocket, I go back and get one at the earliest time. It is the same feeling to me as if I drove off with my pants still at home.
I use my folder all day to "adjust" trim cuts, sharpen my carpentry pencils, cut plugs (truly, whittling a hole plug is a lost art), clean up mortises, open packages, cut the V notch in my cigars, cuts open product manual bags and envelopes, slices off imperfection in trim for quicker sanding, cut binding rope and plastic, cut sand paper, and on an on.
Some years ago, we had our kitchen remodeled. Total gut, right down to the plywood subfloor. The contractor team doing the work didn't carry a knife between all of them. They all had the Lowes/Home Depot Husky folding utility knives. Husky, Super Knife, Brand X, they seem to have replaced the traditional pocket knife among the working men.
I have to give you that one. And truthfully, I am the only contractor I know that considers a good pocket knife a tool of the trade, part of the every day kit. It used to be that almost all the trades guys had some kind of folder in their pocket, most usually some kind of CASE medium stockman. Over the years I couldn't tell you how many of those I have seen, starting back when I entered the trades in '71.
Now, only one of my contractor buddies carries a knife, and he is a 75 year old country boy. I can't think of one guy that carries a folder, not even through my associated sub contractors. That's really sad to me as working in the trades we can carry any knife we want, regardless of size or design. We don't have all the crying and carrying on so many find in the office environment when a pen knife is spotted.
I don't think folks here really understand how small the traditional community has become. And on that same line, I have a huge disappointment in my nephew, who at 12 has no interest at all in knives. He is a successful and energetic Boy Scout, and at his level can carry an approved knife at meetings and when camping. Neither him or his buddies really like any kind of knife, not even many of the modern stylings.
I got him a great little knife, and it was all I could to keep from buying him a chest full for Christmas. However, his Dad is not a knife guy, so his son is not a knife guy. In fact, my nephew doesn't always know where his knives (he has two) are! I had two at his age as well, my BSA knife and a Boker stockman. Oh the decisions a boy had to make when we could still carry knives to school! I carried a knife all through school until I graduated, used it at my afternoon job, and it just stayed in my jeans during the summer.
So it is very painful for me to ask my nephew, "hey buddy, you still using that knife I got you?" only to have him answer, "yeah, it's around here somewhere....".
Ouch.
