I know this has been discussed before, but I can't find the thread. How would you rank these old makers for steel quality? Barton, Swan, Berg, Witherby (Winsted Edge Tool), Greenlee, Shapleigh, Stanley Everlast, and Stanley sockets.

The reason I ask, is that I have several of each of those brands, a full set of Bergs, and a bunch of others that are good enough for opening a paint bucket, or loaning to my wife. I have the Bergs ground at 22.5 degrees, which works well for paring, but I'm toying with the idea of accumulating a full set of one of the other makers to grind at 30 degrees for chopping. Right now, I have several favorites in that group that I do that with. Basically, it's probably a subliminal excuse to buy more old chisels, but...

So, what do you think is the best old chisel brand?
