Most Chinese hammers and vices are cast and not forged. If you use the cheap stuff remember your safety glasses. US made jack stands are hard to come by. Check OTC labels or Lincoln/Walker. I always recommended sizing up if buying Chinese stands. If you think all you need is 3 ton, buy 6 ton. I won't use anything less for working on cars. 10 or 12 ton for your safety. The broader base on the heavier ones is much safer.
