There has just been a discussion of this over in
rec.crafts.metalworking. I could be wrong, but after a quick look
through the Sears website I found no mention of the Craftsman tool
lifetime warranty anywhere. They used to hype it quite a bit...

Guess I may to have to start buying tools again, haven't done that since
the 70's. I've just been returning the broken/worn ones over and over,
it was a good deal!

Kinda of sad in a way, for years now that was the last remaining reason
to go near their stores.
