KD Tools used to make Craftsman wrenches and ratchets.KD started sourcing from Taiwan for its tools,then dropped their handtool line altogether (Gearwrench is the new name of the company,they still make filter wrenches,Gearwrench boxed wrenches and such but no screwdrivers,ratchets,pliers...).That left Sears without a supplier.And like everybody else with homebrand tools,picked the cheapest suppliers overseas to affix their Craftsman name to.The "Performance Tool" line of tools is basically the same that you get from everyone else that gets them from Taiwan (HF,Husky,Kobalt....)....they are pretty much the same now.However,there are 2 grades of China tools...the cheapos that come in PT sets (sockets primarily) and the ones sold separately (noticeably thicker and shinier chrome).Still,no old KD/New Britian/Napa Hand Tools/Craftsman level though.
