The DMT® Diamond Mini-Sharp® is a Diamond Whetstone™ that travels with you. A folding handle protects the stone when it is not in use, and the key chain swivel ring lets you carry it on your keys, a zipper pull or a backpack.
This Fine model uses 25 micron (600 mesh) diamond, DMT's red grit, to restore a fine, razor-sharp edge on knives and tools that are slightly dull. Many users treat it as an all-purpose sharpener. DMT's micronized monocrystalline diamond surface sharpens faster and more easily than conventional stones, and no messy oil is needed: sharpen dry or with water. Made in the USA.
