For spending MY money country of origin is no so much the issue with me as is the quality of craftsmenship and components that went into it.
For new, that would be USA and European where manufacturing is a Team Sport. The US has several companies compeating, trying to make a living and make
their name mean something - like a team. The same in Germany, Switzerland and the rest of Europe. Pride in their country and pride in their "team" (ie company).
A Chinese knife to me is just a chunk of mediocre steel made as "cheap" as possible, with any logo required to sell it stamped on, to be not much more than eye candy. Would they ever put "Norinco" on them them to shout to the world "Hey we made this knife and we are proud of it!" ? I doubt it. Every effort is made to cover it up. I've yet to see
anything made in China because they could make it
better. (This is especially true for electronics.) "They're disposable" is the best thing I can say about them.
Granted, there have been plenty of "cheap" USA and European knives as well, but even they tend to have some history or reason behind them and those companies either improve or die off.
Even though a SAK is not
the best steel, the fit and finish is consistant, the tools are useful (last week I used both screw drivers, both blades, and the toothpic on mine

) and it screems "quality".
The only thing I avoid (for myself) in knives are "collector" knives. I don't like collecting items that were made for collecting - I want the real deal. This doesn't mean I will throw away a gift, but I'll only keep it as long as I want to remember that "so & so gave me this for Christmas one year".
Sorry if this was rant-y
