Knife users who are truly in tune with their cutting tools do not let them get dull; they maintain their edges with frequent "touch-up" sharpenings. Specifically designed for this type of diligence, the Galley-V has a compact, high-impact-plastic base that can be clamped or even permanently mounted to a countertop or other work surface. The base measures 6" long and 2" wide. Star-shaped holes in the base position the sharpener's fine ceramic rods at a 20-degree angle (10 degrees per side) to easily create thin, ultra-keen edges on all your knives, especially kitchen knives. The extra-long stones (12" length) are ideal for sharpening large knives and can be rotated to orient their edges to quickly sharpen serrated blades. They are also easily cleaned with ordinary household cleanser.
