DMT® offers a full product line of sharpeners with a variety of surface composition. Some products are tailored in shape and size for specific sharpening needs. The interrupted and continuous surfaces are layered in micronized Monocrystalline diamond embedded in nickel, a DMT® proprietary process. Diamond as we know it, is the hardest substance and can sharpen or hone any material (more on this). Our new line of unbreakable ceramic sharpeners are best used for putting a polished edge on a tool after it has been sharpened by a more coarse diamond grit.

When compared with conventional sharpening stones, all DMT® products work faster and sharpen exceedingly quick using light pressure.. and they remain flat! It is important to note that all DMT® diamond products are manufactured to the same high standard using the same high-quality monocrystalline diamond that makes sharpening with DMT® superior. Therefore the difference between the two diamond product lines becomes a matter of preference to the user.

These products carry our signature polka-dot pattern surfaces. The polka dots are slightly recessed so that during sharpening the metal fines (known as swarf) and small amount of material that is being removed will fall into the polka dots and remain out of the way of the sharpening surface keeping the sharpening surface performing.

DMT Interrupted Surface Product Lines

Continuous diamond surface sharpeners are preferred when sharpening small-pointed tools and can be used for knife and tool sharpening, honing and deburring as well. On an interrupted surface the point of a small tool may get caught in a recess and damage the surface of the sharpener. DMT® therefore recommends that you use a continuous diamond or ceramic surface for these types of tools.

*NEW* UNBREAKABLE Ceramic! Our new Ceramic and Ceramic Diamond SHARPENERS are our latest innovation and are the perfect compliment to your assortment of sharpening tools. The patented CeraFuse™ process transfoms the surface of aluminum to an extremely hard dense aluminum oxide that has the same properties of solid ceramic materials. With a finer grit than our bonded diamond products, they are unbreakable, wear resistant, light and non-porous. Our ceramic sharpeners are the next step to achieving a polished edge.
