Shaped like a duck’s foot, the Golden Stone™ is a compact, versatile sharpening device that automatically sets the proper sharpening angle. Hold it by the narrow end and place the scalloped end on a flat surface. Tilting the stone from side to side creates a 20-degree sharpening angle on the outer edges. Just keep the plane of your blade vertical and draw the edge alternately along each side to sharpen. The included ABS plastic base reduces that angle to 30 degrees for keener edges and thinner, high-performance knives. Other features allow easy sharpening of scissors, serrated edges, and pointed objects and its suede carry case also acts as a non-slip tabletop pad.
