How do I keep my router bits sharp? Local companies only want to sell me new ones.
Carol Reed: Few sharpeners do router bits. Those that do produce unpredictable results. For the most part, they are inexpensive enough to buy new when they are truly dull. Keep them pristine clean and separate from one another. Touch them up with a diamond slip stick if necessary.
John Brock: I touch mine up using a small, thin diamond sharpening stick that lives in my apron pocket.
Mark Hensley: I use diamond paddles. I place the bit flat side to the paddle and stroke it back and forth.
