I prefer to not buy Chinese made products when possible. With knives there are plenty of alternatives. The Chinese government is not a friend of the United States.
The Spyderco Tenacious appears to be a well made knife and certainly has features common to Spyderco knives so I would say that it is a real Spyderco.
I'm just sorry that production of the Tenacious model is in China instead of here or Japan.
While I totally agree and see where your coming from, I bet there are at least 20 items in your home right now made in China. I try to avoid it when possible but sometimes even the Chinese make a good product. This Tenacious is one heck of a knife. I carry it waaaay more than my Delica 4.
