I have several 10 inch circular saw blades that could use sharpening. Usually I just buy a new blade, but now I have 7 or 8 dull carbide blades and it seems crazy to just buy another one because it is sharp. Does anyone know a place in CR that does sharpen blades, and if so, how much does it cost? Not finding a lot on the internet. So far E & J Tool grinding looks the most promising, but I can't find anything about them besides a phone number and address.
