Great value. I'm not very experienced,.but these cut nicely, as well.as the ones that came.with my lathe. I'm optimistic that these will need less sharpening as I'm turning. They don't seem to leave as smooth a finish as my traditional HSS chisels and I haven't had to sharpen them yet, but I'm thinking a few locks with diamond lapping stick should do it. They seem nicely made and I'm cautiously optimistic.
