If you go to the Spyderco Forum and run a search for Sal's explanation of the Tenacious and its raison d'etre, he will explain that it was because of certain retail establishments wanting a lower price point Spyderco. I will bet you start to see the Tenacious in Walmart as the NativeProbably not PC to carry US made products anymore so they're phasing them out.
