This knife sharpener earned The Best rating from the Hammacher Schlemmer Institute because it produced the sharpest, most resilient edges. Knife blades were dulled by running them along bone 250 times prior to testing. The Best model returned knife edges to sharp points that diced onions and chopped root vegetables with little effort, unlike lesser sharpeners that created edges that required great force to penetrate even soft fruit. It was also rated as having superior build quality thanks to its sturdy metal casing and a suction cup baseplate that kept the unit secure during sharpening. The Best Knife Sharpener also won for its list of features including an auto-adjusting sharpening angle (from 12 1/2 to 22 1/2) and its versatility that allows it to be used on single-edge, double-edge, and wide-tooth serrated knives. Black or Silver. 3 1/2" L x 4 1/2" H x 3 1/2" D. (1 1/4 lbs.)
