The Messermeister Pull Through Sharpener has become the honing (alignment) tool of choice for millions of Americans. One of the worst things people can do is pull a knife blade edge through a fixed V or set of cross rods because it is the same as scraping the sides of the edge against any fixed object. Messermeister introduces their Pull Through Sharpener with moving wheels, which lessens the scraping effect. The 2 stage honing and sharpening tool has a fine diamond wheel (for fine sharpening) and a ceramic wheel (for fine honing). Both wheels provide the least abrasive resistance and therefore are kinder and gentler to the knife edge. Available in our Messermeister blue. (Not recommended on our fine edge elite knives or our Japanese knives.).
