Taiwan is the best of Asia for metal stuff, they make 67% of the worlds threaded fasteners, so tools would be no problemo.
Taiwan is good. Armstrong does not exist. Proto USA is better (Proto also makes some tools in Taiwan!)
It's good, Tekton and Astro Pneumatic make awesome tools in Taiwan. However If I want Taiwan, I can get it at Princess Auto.
I understand OP's concerns. I'm not buying Williams to get the same quality I can get at a box store. I'm buying Williams because I care about COO. Most well known USA tool companies have low cost import lines to avoid sticker shock on box store shelves, even companies that market COO heavily like Estwing.
