Split Screen Diamond Stones. With three layers of monocrystalline diamond, these extra-wide Split Screen Diamond Stones will give you a sharp, well-honed blade on knives, gouges, chisels, and fine pointed tools. Also great for sharpening HSS and carbon! The fast cutting surface pattern is self-clearing and stays flat. The continuous diamond "micro pad" (the non-patterned area in the corner of the stone) is ideal for sharpening very small tools. These stones may be used with or without water. Stone may be removed from non-skid base.
Available in Fine or Coarse, each measuring 21/2" x 6".
