I bought several used SAK's out of buckets of knives seized at airports and court houses. I paid $3 for the little Classics like you described and about $5-$7 or a little more for larger sizes. Both Victorinox and Wenger knives were in those buckets. But only SAK's. I guess someone sorted out other brands and types. I bought several styles, from Classics to a SwissChamp.
Some needed scratches polished off by hand with Simichrome, and I still need to finish polishing a couple. May see what Swiss Army Brands would charge to refinish the blades and maybe buff one or two handles or replace them. The scales snap on and off and they have replacements. And I need a tweezer or two.
But I was able to handpick knives that were all in quite good shape. I feel a little bad about it, because the knives probably meant quite a bit to some of those who had to give them up. One was from the USAF Academy, a couple others from other universities. And there are a few with advertising logos.
I have a couple of my favorite Spartan models that look as good as new ones do after being carried in a pocket for a few months. The only wear is that the bright shine on the handles has dulled a little.
These are the greatest knife values I've seen. And the seller said that interest in them was low and it took him a long time to sell many. I was into those buckets like the proverbial kid in a candy store. I love SAK's!
BTW, several members have made posts about carrying other things in the pocket with their knives. Don't carry anything in your pocket but the knife and handkerchief. That avoids unsightly scratches.
Other items go in the other trousers pocket.
