At 10" long and 4" wide, this DMT® diamond bench stone is the largest diamond bench stone we carry.

DMT diamond sharpeners are well-known for their superior quality and versatility. Engineered to be flattest sharpeners on the market, they are easy-to-use, produce consistent results and sharpen in a fraction of the time required by other methods. The extra-large diamond surfaces of this double-sided 10" x 4" DuoSharp® stone features DMT’s famous interrupted diamond surface. The surface sharpens very quickly because the metal filings are quickly removed from the sharpening surface. The extra-large flat surface works well when you are sharpening large tools or if you just prefer the ease of using a larger sharpening surface. 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, Extra-Fine/Coarse 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 10" DuoSharp Diamond Kit.

Uses

The 10" diamond stone is versatile because it can sharpen almost any size tool. The large size gives it the ability to sharpen tools as large as an axe without any trouble. However, the large size of this stone is not just limited to large tools. The long length of this tool allows for much longer controlled strokes with even small knives. The long strokes promote fast and easier sharpening.

We recommend this DuoSharp® sharpening stone for woodworking tools, kitchen cutlery, outdoor knives, and axes.

Advice

The extra coarse/coarse stone is my absolute favorite stone when it comes to sharpening a heavily nicked edge or flattening the back of a chisel or plane iron. Because the diamonds cut so quickly, this stone is a real time saver. If you can afford to splurge on a stone, this one is great to have around. ~John

Q#. What is the size of the stone?

A#. The total size of the abrasive area on this stone is 10" by 4". Because this stone is double sided, the two size add to a total abrasive area of 80 square inches. If you compare this to a single sided 6" by 2" stone (12 square inches) you can really appreciate the size of this stone.
