Seki Japan Chef Knife Sharpening Rod, 6 Inch, Durable Ceramic Honing Steel Knife Sharpener (150mm)

When a cutting quality becomes bad, you can sharpen a knife without damaging the blade. The fine ceramic whetstone is non consumable no matter how much you use. It will stay the original round rod condition. Because of its round shape, you sharpen one point of the surface, so it enables you to sharpen from different angles. If iron sticks to the whetstone while sharpening, you can wash it out with water easily. You can sharpen a variety of cutlery (scissors, nail clipper, steak knife, mowing sickle) which are impossible or difficult to sharpen with a conventional one.
