Care and Use of DMT Diamond Sharpeners

All models are designed to be used dry or with water so there are no messy oils and extensive clean up to worry about. Always clean the DMT sharpening surface after sharpening. Rinse surface with water and wipe dry. After several sharpenings, clean more thoroughly with a mild abrasive and brush; rinse surface with water and wipe dry.

Always put away dry and store in a dry environment. Use leafing (paper towels, cloth, plastic storage bag) in between your bench stones to prevent abrasive sides from rubbing.

About Sharpening with DMT

Get the Most out of your DMT Sharpener

There is a ‘break-in’ period for your diamond stone. Initially, it will feel especially rough but will smooth over time without impacting performance. Let the diamonds do the work; just light strokes with the edge to sharpen, same number of strokes each side. Approximately 5 or 6 strokes per side (depending upon condition of edge) compared to 30 strokes per side on a conventional stone, saving time and extending the life of the knife or tool. Start with a coarser grit for damaged or dull edges and work to finer grits. The work the edge is to do will help you determine the grit needed: Rough work, end with coarse grit (cutting cardboard); finer work, work through finer grits (food preparation).
