Last year I purchased the 6 pc WoodRiver chisel set with the Bubinga handles. I like them very much however I regret buying the 6 pc set. As others have mentioned, I mostly use 1/4", 3/8", and 3/4" chisels, the 5/8" chisel I could do without, it never gets used. A 4 pc set would have served me just as well and saved me a few dollars. The alloy used in these chisels (in my experience) is slightly brittle out of the box, once the chisel is sharpened a few times that brittleness is lessened. I also purchased a set of Narex chisels (2 sets actually) and like these chisels as well, great value for the money and these chisels have a nice slim cross section.
