Went to the local show today with my buddy for the usual search for things we don't realize we need. He pointed out a str8 in the back of a cutlery dealer's display case. That one had seen too much stone work, but the dealer asked if I'd like to see some others he just got. Well...a Keen Kutter in great shape and some other nice blades (including a Craftsman), but I explained that I was after a 6/8 or bigger. This led me to tell him about blade sizes and wear patterns (he's a knife expert not up on str8s). He pulled the rest of them out and HOT DAMN, a virtually mint 7/8 Puma!! I reluctantly gave him the exorbitant sum of $30 for it and barely kept from cackling in glee as I strode away. I could of scored some nice 5/8s from him, but I have enough of those. (His most expensive blade was the Craftsman at $40.)
Moral of the story: you never know what sort of shaving gems you might stumble onto at a gun show.
