I don't know. Regardless of how great the prices may be, it does feel wrong.
Rarely does these auctions have nicer knives, but sometimes they do. It always makes me feel bad to see something that could have been someone's grandfather's knife that they cherish and just forgot it was in their pocket.
I was out with a friend recently and somehow her hand made its way into my pocket and she asked "do you always carry a knife?" I honestly didn't know I had it on me. It's become so natural over the years to just put it in my pocket with whatever else I've got. I would probably be in tears if at the airport security check I realized that I still had the Buck 110 my grandfather gave me on my belt. Sure it's not a top of the line knife, but it means a lot to me and I wouldn't want it to end up on ebay in a box of assorted crap.
No... I don't think, no matter what the knives or the price, I could bid on one of these.
