DMT Dia-Sharp D12, 12" x 3" Diamond Sharpening Stone!
The extra large DMT sharpening stone is perfect for larger knives and tools. The large 12" x 3" size allows for longer strokes and gets the job done faster than smaller stones.
This extra-large combination stone is available in 2 grit configurations. The D12CX is 220/325 grit. The D12FE is 600/1200 grit. We also have them available in kits.
The Dia Sharp also comes with the new DMT Magnabase that holds the stone in place and provides knuckle clearance while sharpenig. The base is magnetic making changing grits a snap. The Magnabase also works with all DiaSharp stones.
