I've not spotted fake knives being offered on eBay, but something that borders on fraud. The eBay title might be "Spyderco Sage", but it you look closely at the photo or read the entire ad, you'll see what is accurately being described is a lesser Spyderco model, perhaps a Tenacious. I see that often enough that now I "ask" the seller a question. In each case I get a "sorry, incorrect listing, mistake, etc" sort of reply.....but I never get the feeling the ad will be changed or withdrawn. This happens also with other items on eBay; shows we must be diligent. I used to try to notify eBay of these apparent "errors", but never received any reply, so figured they don't really care about those. Caveat emptor.
