This blade didn't do what I was hoping for, but it still seems a good blade. steel for hardening. It had a convincing dent, but neither it nor my cheap saw did the job. Now I guess I need something with a lot fewer teeth. e: I've now upgraded from 3 to 4 stars after using this on hardwood. This lightweight blade is well worth the money on hardwood, but I've since also tried it on a 3/8 zinc plated steel shank with no success except a dent and heating.
