I have also wondered about Northern's warranty and parts availability, that said I have a few Klutch 1/2 impact socket sets and have thoroughly beat the snot out of them with no issues. My most recent delivery is an SAE deep impact set that had no COO (country of origin) on the package or website. I will say this set looks a lot like the Gearwrench 3/8 set I own with roll stamped sizes, smooth finish, full profile, and laser etching. Too bad I have all the sets I can use, wish my older Klutch sets looked like these new ones. If anyone gets a new set please post if they have the sizes roll stamped. I agree with dlundblad, Taiwan or China, just like everyone else.
