The swap meet thing is interesting to me, thanks for sharing. This emphasizes my query here on new vs old tools. It got me thinking... would you rather buy an old USA made Craftsman wrench or a new Gearwrench? Or a new Tekton? Does the USA made aspect of the old craftsman mean better quality given the 20+ years between when they were made? Or even further, say the tool is from the 80's, the 60's, etc.
My Craftsman tools are from the 90s and early 2000s. Most are USA (~ 90%), but the more recent are China or other. They have done me well and I have no complaints, so my question relates more to a technical answer than anything as I personally do not see the difference, at least as of now.
