are they the smooth shiney ones or the dull(or shiney) textured ones?
the shiney ones are a bit longer. the textured ones are a little shorter(not close to stubbies short).
if they're more than about 15 years old they probably are made in USA.
if the "H" in husky has an extended line as in the right vertical line in the letter "H" looks like a letter "L" its a good chance it's made in USA.
and of course what you intend to do w/ 'em depends, but I wouldn't be afraid to use 'em for home use.
I have some I use at home and I really use 'em rough. right, but rough

the only one I messed up was 'cause I used it wrong like a dummy.
and when I said rough I do take care of my stuff, but in my garage i'm working on 50/60/70 year old cars/motorcycles/bicycles
