This Wusthof Whetstone is double sided, grits 1000 and 3000 (Japanese Industrial Standard). Sharpen all straight edge knives using this traditional method. Make sure your knife is clean before sharpening as a build up of grease and oils will effect the surface of the stone. Use when you're knives start to dull, maintaining an edge is the best way to keep your knives in top condition.
