I work in a fortune 500 manufacturing plant where tools are provided. The company buys the US made Craftsman toolboxes and tools. One could argue the point that our maintenance guys are not wrenching 24-7 or at least not while production is running, so the statement could be made those tools don’t get used as much as an automotive mechanic. However, the guys in the engineering lab are constantly using those tools day in and day out and while things break and wear out it’s simply not the norm, it’s the exception when the tools break.
I’m not interested in arguing about which tool brand is better or anything like that. All I am saying is that US-made craftsman can get the job done and they’re not the worst thing out there. If I was a professional mechanic I would certainly own more Mac and Snap-on. To me it highlights the fact that US-made craftsman tools are great for the serious do it yourself type beause it is a good balance between cost and quality, which is the reason for the popularity.
OP, eBay and flea markets/garage sales.
