The Pronto is the fastest 2-Stage manual sharpener on the market today. In seconds, it puts a razor-sharp, stronger, more durable arch-shaped edge on both straight edge and serrated knives. The Pronto's CrissCross technology uses 100% diamond abrasive wheels that sharpen simultaneously "into" and "out of" the knife edge for a superior burr-free edge with lots of bite. Compact, easy to use and quiet, the Pronto can be conveniently stored in a drawer. It features a "Soft Touch" handle for an easy, secure grip. Engineered and assembled in the USA.
