DESIGNED TO KEEP YOUR SHARPENING STONE IN OPTIMAL CONDITION! Maintaining a flat and level whetstone or waterstone is essential to being able to sharpening your knives evenly for peak performance. Our flattening stone’s coarse grit silicon carbide surface is designed to precisely repair and level your whetstone in a matter of seconds!


THE PERFECT FLATTENING STONE! Our repair stone comes with factory precision cut grooves that are specially designed to collect material removed from your whetstone. This unique groove feature provides a much more accurate leveling process. Also, our leveling stone’s large abrasive surface is perfectly size matched to expediently accomplish the flattening process with an efficient number of passes. Don’t be fooled by smaller nagura stones that cannot provide the same degree of precision!


ENGINEERED TO PERFORM! With high performance, professional cutting tools in mind, we’ve carefully chosen only the most appropriate silicon carbide material and perfectly proportioned dimensions to ensure that your whetstone will quickly return to its original condition without any extra waste. With even and light hand pressure (and no aggressive force required), our flattener stone quickly and easily removes any remaining embedded steel particles from previous knife sharpening operations.
