Too bad they have all let the quality go to crap. Nicholson files aren't worth buying anymore. Stanley started out as Stanley Rule and Level Company, then expanded into other tools. They were the top maker of planes for about 100 years, until the late '60's. They also had really good chisels in that time frame. The new chisels and planes, though patterned after the old ones, don't compare for quality. Most of the time it's the details, not the materials, that are the issue. Stanley needs to tighten quality control in their manufacturing, and relook at their old designs. The new 750 series chisels are too heavy in the edges.
Milwaukee seems to be more plastic than metal in their corded tools. Most, if not all, of the others seem to be the same way. The NAREX brand bench chisels don't seem too bad for the price.
I could fill a page or two with a rant on this subject.
