Besides Mechanic named John, are there very many mechanics who use cheapie imported HF or other such tools for their daily work? I have to imagine the savings would be significant, I just wonder if they would hold up. Hell even if you have to buy a couple new sockets a year because you wear them out it would almost seem to make sense to buy the import stuff (from a $$ standpoint). In my personal use at home I lose more than I break, come to think of it I've actually never broken a Sears or Dollar Store socket.
Sure, I use HF tools 5 days a week, or nearly so. I have a whole pile of them (which seems to multiply by cellular division, probably due to those incessant sales). But they're carefully chosen, for particular things. I've mentioned before how much I love their 18 piece brake kit, and tools like the 2 pound brass hammer work just as well at hitting things as any brass hammer from Craftsman, Snap-On, or DARPA. The 1/4" and 3/8" air ratchets and vacuum bleeder work great. Chrome sockets, definitely not. Craftsman (which I'm very happy with), getting some S-K, etc. Impact sockets, I'm not getting Craftsman (and I have a Gearwrench set that I'm not very happy with), I'm sticking with Snap-On, etc. Combination spanners, as I've said before I'm not satisfied with my Craftsman raised panels for work use, but I love NAPA and Gearwrench, in addition to my Snap-On Flank Drive Plus (which are like magic when I need an open end, in that case I skip straight over the NAPA/Gearwrench).
Point is, cheap tools work great,
for some applications. Other applications, mid-priced tools are worth it, and work great. And others, the high-end tools really are a good investment, and show their value. You just have to figure out what you need. Making blanket assessments across all applications like, "I'm not buying off a tool truck...for
anything!" or "I won't buy
any tool made outside the United States!" or "Harbor Freight can supply
every tool in my shop, I don't need any other sources!" probably isn't the most effective use of your money or toolbox space. Even MechanicNamedJohn said he has a few things from other sources.
