DMT's Longest Stone

DMT's longest continuous double-sided diamond bench stone surface accommodates a variety of tools and blades. The stone measures 12" long and 3" wide. That 12" length provides plenty of room for long, smooth strokes for even the longest of knives. And if tools are your thing, the 3" width is more than enough for even large hand plane blades.

Two Grits on One Stone

The DMT 12" Dia-Sharp stones are double-sided, with two grits on each stone, making the most of every inch of space for maximum efficiency.

Choose from Three Options

The DMT 12" Dia-Sharp Stone With Universal Base is available in three different grit combinations:

• Extra-Fine 1200 Grit/Fine 600 Grit
• Fine 600 Grit/Coarse 325 Grit
• Coarse 325 Grit/Extra-Coarse 220 Grit

With DMT Universal Sharpening Base

Each 12" Double-Sided Dia-Sharp stone includes a DMT Universal Sharpening Base. This versatile base truly is universal. Not only does it hold the 12" x 3" Dia-Sharp stones, it also holds any DMT Whetstones, DuoSharp Stones, and Dia-Sharp Stones. Additionally, this base will hold many non-DMT brand stones from 4" to 12" Long.

DMT Dia-Sharp Stones are made in the USA. The Universal Sharpening Base is made in China.
