Ah ok. I was talking with the (smoking hot) chick at Spyderco about the value folders like that. Made in China, not as great steel, but still covered by the Spyderco warranty unlike the Byrd series of knives.
I carried the Tenacious for two years and used it daily, never had a problem with the steel (no rusting or anything even though I live next to the sea) it stays sharp if you take care of it too.
The Resilience is pretty much a Tenacious with a bigger blade and the same 8CR13Mov steel.
If it has the Spyderco logo I trust the quality no matter where it's made (USA, Japan, China, Italy etc).
