I ran across a YouTube (actually several) of folks using the HF saw blade sharpener on carbide blades. http://www.harborfreight.com/120-vol...ner-96687.html Has anyone here have any experience with it? Looks like it just grinds the face and couldn't be used for any triple chip grinds. Probably wouldn't want to use it on your $100 blades either. Interesting it comes with a diamond blade for the rough cut and an emery blade for the polish. For under $50 it would pay for itself on 2 or 3 blade sharpenings. Cutting a lot of aluminum oxide finished flooring really dulls them fast and they are not real critical cuts nor something I use my good blades on. I have a number of older blades laying around that I wouldn't pay to resharpen, but might get some use if they were sharp.
