Check the listing for details. Norton Combination Grit Waterstone, 1000 / 8000. Condition: New. Listed at 102.86 USD. Out of all the commonly used sharpening methods, waterstones are generally considered to give the best results. And out of all the waterstones on the market, both manmade and natural, Norton stones are tops for performance. Using water as the lubricant, waterstones develop a fast cutting slurry. By going through a carefully planned sequence of sharpening (ever finer grits), tools can be brought to razor sharpness with great efficiency.Because of the softness of the material, waterstones do wear concave with use and require periodic re-flattening. We recommend Norton's Flattening (#64236) and Prep (#64240) Stones (sold separately) for flattening and conditioning of waterstones. Waterstone is 8" x 3" x 1" and comes in an individual plastic case. USA
