The Spyderco Galley-V Sharpening System comes with two fine-grit ceramic rods and an ABS plastic base with set angle guides. The Galley-V system is made to hone a wicked, 20-degree edge on serrated and plain-edged knives. The process is as easy as attaching (via clamps, screws, etc.) the base to your surface of choice, positioning the rods, and pushing the edge of your knife down along them. Detailed instructions, tips and tricks, and general sharpening knowledge are contained in the included instructions. Experience the pure satisfaction of cutting with a knife sharpened by your own hand.
