Lowe's sells Craftsman tools and supposedly honors the warranty. Unfortunately current Craftsman tools are "M.I.C."
Phil, you may be right about no defects. Just overtorqued. Yeah, maybe too much a$$ behind that kick.
The foot is OK though. I definitely ducked when it popped.
Stewart-Walden (then called Walden-Worchester) was one of the big 3 tool makers back in the '20''s, along with the upstart Snap-on and Blackhawk. They made quality stuff, but have long ago gotten out of the socket business.
