I must have 15 table saw blades of various sizes and designs. Is it practical for me to learn how to sharpen them or should I just keep buying new ones???? Some are carbide tipped and some are not. What tools would be required. How do you test for sharpness? I can feel the cutting difference when I put a new blade in but when comparing two older blades, how can I tell which is sharper.
TIA
