Mudtools Diamond Burrs
These Diamond Sharpening Burrs are just the thing to refresh and old blade. Use this burr bit with a Dremel, flex shaft or drill that will hold the 1/8″ shaft. The burrs have a fine coating of diamond dust, so they cut quickly and smoothly. One light pass over the sharpened side should be enough to resharpen most blades. Can also be used to remove glaze drips from the bottoms of pots.
