jackknife,
I think demographics contributes to brands used by many as well.
Case is what I grew up with.
Heck, I had a Case Peanut tossed into my dresser drawer crib after the stork dropped me into it. *grin*.
Case was what hardware stores , feed and seed stores and everyone else stocked, and folks really used , from home, farms, ranches , plant jobs, to anything.
Shrade-Walden, then later Shrade was seen and used.
No offense, but a Case was the good knife, and Old Timer the one folks did not care if it got messed up or not.
Camillus was another, as they did the GI Demo knife and with the Military presence near, this was not only used by them, civilians got ahold of one, for all sorts of uses, much like a SAK is today.
Emergency knife, tossed in a truck, or vehicle, or in the storm cellar...
Kabar, again, with Military, Kabar was a normal fixture.
Imperial, was another popular knife, and it served a lot of folks.
Odd, but folks that could not afford a Case, would buy a Imperial, before they would a Old Timer.
Best guess, is some of these ladies and gents wanted a good looking knife, like a imitation pearl , for a lady and Old Timer did not offer anything but the traditional "brown" handles.
Hi-Falutin' knives were Hen & Rooster ( and as time has passed, those knives are more money now!).
Boker was another, as some of the folks I grew up with, went out of the USA, and these Hen & Roosters and Bokers they shared about with us, and would bring back.
This during the Cold War and jackknife understands where I am coming from.
Buck, Remington and some others, I never saw, only reason we knew they existed was magazine ads , or if someone visited from out of town.
SAKs - nobody had one, was interested in one, did not care one iota about one.
Not even those that has been abroad, and actually seen one, even used one.
"It is a red plastic knife with that nasty stainless steel and no way near as tough as a Camillus made GI Demo knife" - is what the shared, and was repeated often, and I was a senior in HS when I saw one and shrugged and showed that fella what a "real" knife was, my Case Slimline Trapper with CV blades.
Buck 110s started showing up.
Seriously, even the Bikers here used Case knives, folding knives like Trappers and Sodbusters.
Now this funny , still true, heck I was did it.
This here "lockback" idear, got talked up.
So a couple of mentors and I got a Case Mako Shark.
Used it once maybe twice, *shrugged* and put them up.
We did not like that Tru-Sharp, or the lock, and liked our CV blades on Case knives, such as Trappers, Stockmans and the Peanut (we had that one always, along with a bigger knife, how raised).
Bikers here got some Case Mako Sharks too, for some reason that one fit hands better.
They too did not like, and put them up and went back to what Case knife they had been doing.
Bunch of Bikers showed up for something or another and had Buck 110s.
"Ya'll must be Yankees, as you ain't got a Case pocket knife" - our Bikers said to them.
It was all good, really funny , but true.
"Ya'll seen Queens?" northern bikers asked.
"No dude, we have Presidents and Generals here in the South, heck didn't ya hear, we broke off from England some years back".
Referring to the Queen of England and the War of Independence.
Case to me, has always offered the patterns I prefer with the steel I prefer, which is CV.
Boker and Hen & Rooster, along with Camillus , and others mentioned are a part of my preference.
Currently, Case and Boker ( with carbon steel) are what I prefer.
Moore Maker, out of Texas, is one that interests me, and when some results are reported back, and I get to mess with one, that brand has potential.
SAK?
I might have a Classic SD, and Solo put back, not sure, would have to look.
Classic is supposed to be in a travel kit, Solo in some bag ( hopefully not lost) with some other gear for emergency , that is out of state.
Pocket Pal, who knows where it ended up, it was a emergency back up, and kept in a vehicle and most likely put to use sometime back.
