The DMT Dia-Sharp Diamond Plates are impregnated with diamonds for an aggressive cutting surface. The D8EE is a great plate for refining your edge and is rated 8000 grit. It will cut quickly so little time is needed for finishing your edge. It will still leave a toothy edge which some prefer, especially in a professional setting. These plates have rubber feet attached to keep them from slipping while in use. Measures 8” x 3” x ¾”.
