The DMT Dia-Sharp Extra Fine Diamond Sharpening Stone is a compact continuous-surface stone measuring 4 in x 7/8 in. Its extra-fine diamond face gives pointed tools and small contact areas a full working surface without requiring a larger bench stone, while the slim format is easy to keep with other edge-maintenance gear.
The diamond grit is marked on the side of the stone for quick identification. DMT’s continuous-surface design keeps the abrasive available across the full face, so this is small stone useful for controlled touch-ups and detail work. The stone is made in the United States. Explore more sharpeners.
