I wanted to add some quality chisels to my tool bag and decided to try Stanley chisels. A set of 4 tools costs about the same as an LN tool. The tools had to be adapted/coordinated immediately. All backs were concave and had a coarse twist on them. It took about 15 minutes for the back to be fairly flat on a wet 600 grit rock. The strip left a mirror finish. Now they cut very well. I'm about to have a project where a lot of mahogany material needs to be removed, so I'll be testing the edge retention. Update** I've used these bits on two projects and they continue to impress. The latest project involved hand-carved hard maple swallowtails. They kept their sharpness throughout the project without even polishing it.
