Q: How does this sharpening system work?
You draw the knife through a V-shaped ceramic intersection: the coarse tan wheels remove nicks, and the fine white wheels hone the edge afterward.
70M4601 - Knife Sharpening System

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.

No, laminated-steel knives should be sharpened with a water stone instead, since the wheel geometry isn't suited to that blade construction.
No, this knife sharpening system is built for people who struggle with freehand sharpening methods, since the preset wheels set the angle for you.
