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. And because this stone is double-sided , it is more versatile and cost effective.

The "plus" feature on this stone is the area on the edge of the stone that is continuous diamond material, instead of the traditional interrupted material found on most DMT® diamond stones. The continuous diamond material works on pointed tools where the interrupted material might catch the tip of the tool. A non-skid mat is included with every diamond stone.

Available in Extra Fine/Fine Grit, Fine/Coarse Grit, Fine/Extra Coarse and Coarse/Extra Coarse Grit. The Fine/Extra Coarse is a SharpeningSupplies.com exclusive, it is only available with the base. Made in the USA.

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.

For greater savings, we offer the Extra Coarse/Corase and Fine/Extra Fine as a kit with a base. This kit is called the DMT DuoSharp Plus Diamond Kit. You get all 4 grits.
