I've got a few wrenches I bought when I worked there in the early 1980's. They weren't bad, but nothing overly spectacular either. They still had a lot of name brand products made in the US back then. Not the wrenches, but a lot of other products.
K-Mart was the #1 retailer in the US for a few years, beating out Sears, and Walmart was 3 or 4 at the time.
The food in the cafeteria wasn't bad, and was priced very reasonably. I ate there quite a bit during the 4 or 5 years I worked for them.
Remember the smoky glass inserts they had at the cafeteria? So you could sit there and eat your club sandwich and strawberry Jello without having to stare at people loading up **** into their carts?
K-Mart made socket sets in the 80's from Japan were very decent. I have one set of those. Really, in the 80's hard to find anything made in Japan that was bad in any way. Japan quality was rising in the 70's and it reached the top in the 80's and stayed there. Taiwan was rising in the 80's and reached the top in the later 90's and stayed there. Even Sears sold many tools in the 80's made in Japan. Craftsman was still US then, but Sears brand was often Japan. I have some Sears Japan wrenches from then that are just fine, about same as US Craftsman of that era. - Paul
