Well, those old wrenches have held up better than most of the Craftsman if you've used them in professional service for 25 years. I had those same wrenches, maybe a few years older, and gave up on them for better ones years ago. But, they got the work done when that's what I could afford.
Below is the Professional, Full Polish set they're shipping today, along with comparison to some other wrenches from my box. Sears, in their rush towards bankruptcy, gave me $58 in points last week, so I bought this set for about $50. The best they sell. Good thing it's the best, it's none too good. Poorly broached box ends, too much bevel to the box so you give up nearly 1/8" of grip on the nut. Lobster claw open end. The ignition wrenches they threw in with the set are pathetic. Bad part of that is that the big wrenches are Taiwan made, the ignition ones say USA made on the plastic bag they came in. Nothing stamped on the wrenches themselves.
The other wrenches have been in my box and in use for between 15 and 25 years, except I think the proto has been there for 3 or 4. The best are the Snap on ones. Next is the Williams made Kobalt and the Proto, similar quality but different style (matte vs full polish). Last is the Matco. The Matco, as thick and clumsy as it is, is still better than the new Pro Craftsman.
The last two photo's show the Snap-on and the Matco in comparison to the new Craftsman Full Polish Pro. I'll post pictures of the ignition wrenches compared to good ones in the nest post.
Here's the photo's.
