For all those who have despaired of sharpening knives the traditional way, this is an effective, low-skill alternative.
Using the arranged sets of four coarse wheels and two fine wheels, you only have to draw a knife through the V intersection of the ceramic stones to remove nicks in the blade (on the tan coarse wheels) or to hone it on the fine white wheels.
Better a simple two-stage system at hand than using a dull knife because there is no time to take it to the shop for the full treatment. At just under 8" × 3" and 1 1/4" thick, it stores readily. High-impact plastic frame. Not for use with laminated knives.
