There are many threads about them however, which ones are we talking about satin or full polished versions?
Here's my spin: The satin ones are basically sound no frills wrenches. They're kind of a better finished US Made Craftsman raised panel wrench without the raised panel.
The full polished ones are the true sleepers. Great balance and feel, good fit, off corner engagement on the boxed end, well finished and US made. Now there are two versions of the full polished wrenches. the early first generation from the 1980s looks like they took a satin wrench and polished it. There is a pronounced lip where the open end meets the beam. This version is nothing to write home about and I'd avoid it. However, the newer second generation are much nicer. Better chrome, smooth between beam and open end. Think of them as a standard length version of the Danaher made Craftsman US professional series combination wrenches. I have more than a couple of sets of these wrenches and they have always been my favorites. sadly, production ceased on these wrenches over 5 years ago, Ebay and close out places like Cripe Distributing has some open stock left but, that too will dry up eventually.
