I am not going to say that I know it for fact, but I am pretty sure it is correct. I can't think of an S30V steel blade that does not also say "Golden Colorado USA Earth". A quick look on the Spyderco site tells me that all current S30V steel bladed knives are made in USA. The only exception is the Spyker. It is a joint effort between Spyderco and Kershaw. It does not say where it was made, so I am not sure on this one.
