Why don't you people like having China or Taiwan stamped on the blade? Regardless of whether it's there or not, that's where it was made, and if it's a good enough knife for you to own and carry, why should it bother you? I'm proud to own knives from China and Taiwan that completely destroy the notion of those countries being incapable of making quality cutlery.
Its just a pet peeve of mine. I personally don't like any markings on anything. I don't like to wear clothing that have slogans or the designer's name on it. I've always debadged my cars (debadge = removing car model info and stuff from exterior of car). And I'm not a fan of all the markings on a knife, such as: the manufacter's name, manufaturer's logo (i like the spyder, though), manufactured date, model name, designer's name, steel type, place of manufacture (though I do enjoy the usa, earth stamp), etc... Its just too much stuff, and to think that it inherently drives up the cost of the product. Ironically, this was the first time I wished the model name was on a blade, as sage is my nickname.
Personally, I don't care where its made, its a spyderco and I trust the company. But less stamps would be plus, and I find the way boker used that hidden part of the tang an elegant solution.
