I can help set the record straight on this. Walmart has sold the Spyderco Tenacious as little as 3-4 years ago in stores (they still turn up on my reports now and then) and as long as it says "Sold by Walmart.com" on the website, it's real. We're buying those direct from Spyderco. If it's OpticsPlanet or Outfitter Country or some other third party, personally I'd stay away. I will agree that fakes and stolen/refurbed knives often show up in those third parties' distribution, but not in our direct line. You should see ZT go direct soon as well.
