DMT® diamond sharpeners are known for quality and versatility. Easy to use, they sharpen fast with consistent results. The 8" DuoSharp® Plus Bench Stone is designed with DMT's signature polka-dot (aka interrupted) pattern on an 8" x 2 5/8" base perfect for knives, scissors, tools PLUS the benefits of a continuous diamond area for small and pointed tools. And, because this stone is double-sided, it is more versatile and cost-effective.

The overall size of the DMT® 8" DuoSharp® Plus is very generous at 8" long and 2 5/8" wide. The length is long enough to ensure long strokes of your tool or knife, and the width is wide enough for even larger plane blades. A non-skid mat is included with every diamond stone. Made in the USA.

Available in the following grit combinations: Extra-Fine/Fine Grit, Fine/Coarse Grit, and Coarse/Extra Coarse Grit.

For greater savings, we offer a special value kit with the Extra Coarse/Coarse and Fine/Extra Fine (All 4 Grits), plus a base. This kit is called the DMT DuoSharp Plus Diamond Kit.


The DMT® 8" DuoSharp® Plus is a great combination of size and value. The 8" diamond stone is ideal for just about any knife or tool. The fine/coarse or the fine/extra coarse stones are great stones to own if you're going to own just one stone. The coarse or extra corase side can remove nicks or sharpen very dull knives and tools. The fine side is fine enough for the final edge on kitchen knives or used as an intermediate step before even finer grits. The fine/extra fine stone can be used any time your edge is not damaged or abused. After using the fine grit, the extra fine grit puts an extremely sharp and durable edge on knives and tools. The coarse/extra coarse stone is a good stone to have for coarser work on dull tools and knives.

We recommend the 8" DMT® DuoSharp® for woodworking tools, kitchen cutlery, and outdoor knives.
