Based on a style of manual sharpeners used widely in Europe, Work Sharp, our preferred sharpening partners, have released the first American-made Rolling Knife Sharpener in the U.S. market. Unlike a complicated whetstone or electric sharpener, which require skill or planning to use (no need to soak a whetstone here!), the Work Sharp uses a magnetic angle block and rotating abrasives to bring blades back to razor sharpness. The block comes with four different sharpening angles—15°, 17°, 20° and 25°—to sharpen a wide style of knives. And the three abrasive wheels come in three levels of coarseness: coarse 320 Grit diamond, fine 600 Grit diamond and fine ceramic hone. To use, simply line your knife up against the block on one of the angles, then roll each abrasive along the cutting edge to sharpen, going from most coarse to most fine. We were impressed with the sharpener’s precision performance—dull test knives were returned to out-of-the-box sharpness. And when you’re done, it stores away easily in your drawer.
