This electric knife sharpener produced the sharpest, most resilient edges, thereby earning The Best rating from the Hammacher Schlemmer Institute. Analysts ran knives across a cement block 100 times and then sharpened them with each model. The Best Electric Knife Sharpener ground edges that sliced through a tomato's firm skin and chopped a spaghetti squash on the first pass. Lesser models produced edges that cut ragged tomato slices and required great force to cut the squash. The Best model sharpens knives to a 15º angle--the edge favored by Japanese sushi chefs for its unparalleled sharpness--and creates a patented triple-bevel, arced edge that maintains its sharpness longer than hollow-ground or v-shaped edges. All of the knives were examined under a 4X digital microscope, and The Best model produced the most consistent edges from tip to bolster. The Best model's guide springs automatically hold a knife at the optimal 15º angle while 100% diamond abrasives and stropping discs grind and polish the edge to restore its original sharpness in only one minute. Accommodates straight-edge or serrated knives. 9 1/2" L x 4 1/4" H x 4" D. (4 3/4 lbs.). You can get this at - http://www.hammacher.com
