The overall size of the DMT® 8" DuoSharp® is very generous at 8" long and 2 3/8" 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 (choose from fine/extra fine fine/coarse, or coarse/extra coarse grits), it is more versatile and cost effective.

A non-skid mat is included with every diamond stone.

Available in Extra Fine/Fine Grit Fine/Coarse and Coarse/Extra Coarse Grit. 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 coarse/fine stone is a great stone to own if you are going to own just one stone. The coarse side can remove nicks from 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 great stone to have when you need to sharpen very dull knives and tools because it cuts so fast.

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