3M Adhesive-Backed Sandpaper

For sharpening blades, we recommend the use of a secondary bevel for quick results. With repeated sharpening, this secondary bevel will grow larger and the primary bevel will need to be reestablished. These rolls of adhesive-backed sandpaper can attach to any flat reference surface and, with a honing guide, regrind a bevel back to its primary angle. 80 grit works well for blades that need a lot of work; 180, 220, and 400 grit is used for standard regrinding. Each roll is 2-3/4” wide. 80 grit rolls are 25 yards long; 180, 220, and 400 grit rolls are 45 yards long.
