when I made the rounds in the late 80s and early 90s, there was some surplus left but mostly just boonie hats, old gun holsters and a few surplus knives, but you are right, other stuff was being added that were mostly used old stuff, uniforms, coats, or more camping, law enforcement items (nylon stuff with velcro), old buck sheaths, and cheap knife fantasy and knockoffs. Luckily I knew the owner one store and he would make an effort to order modern knives with good name brands, and a few cheap stuff, but I could always find good stuff there. I also still had a great selection of knives at the local hardware store before it was closed. I worked downtown where I could take my lunch break and check out the knives under glass, the man at the counter was a hunter a good old guy. I got Bokers and Case and he actually saved me save some money, I didn’t have enough for tax for the blackjack model 1-7 in leather handle when they came out, I had exactly 70.00 bucks, he told the cashier just to ring it up as miscellaneous with out tax. Still have it.
