I very rarely buy a used knife-maybe 3 times. I guess I just am not the trustful kind. Anyway about 2 months back I saw a Spyderco Southard with some nice extra's at a good price. I have always really liked the looks of the Southard. I have I black but this was originally a tan with satin blade. The owner had swapped out the stock scale for a carbon fiber and it looks good. I got it pretty quickly and started working it. Open--Close-----. It seemed to be ok. Blade was centered. After too much longer though it started getting less smooth flipping and closing. Then it struck me, this must be one of those Southards with the screwed up washers. I guess the seller figured this was a good time to get rid of it-thus the good price. Anyway, I sent it back to Spyderco thinking maybe they would make it right because it is a known problem. Where I screwed up was leaving the carbon fiber scale on it. Thanks to that it cost me 20 bucks. Spyderco is serious about not modifying your knife. Oh well, at least I will have a kind of new knife. It ism a little disappointing though that this guy sold me what he knew was a problem knife. I don't think I would ever do that.,
