The 4 ceramic rods, stored in the sharpener base, provide a super polish and razor-sharp edge. The fine 4 x 1 (750 grit) diamond stone can be used to hone knives, tools and fishhooks. Handle slides closed. Weight: 7 oz. Dimensions: 7 L x 1-1/2 W x1 D. Cancer and Reproductive Harm- www.P65Warnings.ca.gov. Type: Sharpeners.
