The easiest way to sharpen and maintain your knives. The 2-stage knife sharpener with carbide and ceramic rods is especially suitable for those who are not yet comfortable sharpening with honing steels or whetstones. This knife sharpener quickly delivers good results. Simply place the knife against the guide and pull it through several times. One stage is used for coarse sharpening (for dull blades), and the second stage is for fine sharpening (for roughly sharpened or moderately sharp blades).
