Shaped like a duck’s foot, the Spyderco 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 of the stone. All you have to do is keep the plane of your blade vertical and draw the edge alternately along each side to sharpen. 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. The Golden Stone is easily cleaned with household cleanser, a scouring pad, and water.
