The Forschner 12-in. Oval Diamond Sharpening Steel is a medium grit superior sharpening steel with a hollow rod that is diamond coated to provide maximum sharpness. The oval shape of this steel allows for greater contact area between the diamond sharpening area and the blade. This diamond steel from Forschner will actually remove metal from the knife blade. It can quickly put an edge on a knife that cannot be sharpened with a regular steel. The black nylon handle is comfortable to hold, whether you're right or left handed, the secure grip is non-slip.
