Coarse ceramic sharpening rod, 10". Ideal for resharpening Japanese knives which are no longer responding to a fine hone, or for maintaining German or other European style knives. Works much like a regular butcher steel. This hone is equivalent to 300 grit, which is equivalent to about 800 grit in the Japanese system, so it's coarse, but not overly so. This length is great for just about any kitchen knife, including large chef's knives. Includes a quality black-finished wooden handle and steel hanger. Also consider the Superaser to keep the rod clean and to make it last longer (eventually deposits from the blade will make it even smoother). And be sure to have a fine grit hone on hand before you buy this, to maintain the fine polished edge. If you use the fine hone regularly, you should not have to use this coarse one very often. Made in USA.
