I must agree with Glenn on this issue. IMHO it is not the manufacturer's problem if a item is simply worn out. My first set of real tools came from Montgomery Ward as a college graduation gift in 1969. I still use them today and have had to replace not even one of them due to breakage. I have some Craftsman tools almost as old. I did crack a 1/4 in socket, and it was instantly replaced at no cost in probably '85. The business model of Wards and Sears in the past has been the source of their downfall. They simply made things too good in the first place. Planned obsolescence for a hand tool after 2 months is ridiculous, just as it was for 60 years or more when I got these tools.
