The Byrd Duckfoot sharpening device measures roughly 7" x 3" and offers around 15 square inches of diamond coated sharpening surface for sharpening any tool. The Duckfoot is a steel sharpener with nickel plating to bond the 600 mesh mono-crystaline diamonds. The diamond particles do not require pressing hard when sharpening, in fact if you press too hard you can dislodge the particles and thereby shorten the life of your sharpener. Gentle pressure does it.
The angles and sides on the Duckfoot include: a 1” X 5” flat diamond stone, 3 grooves including a wide radius channel for de-burring and a narrow radius channel for honing pointed objects. By holding it vertically on a tabletop it tilts from one side to the other raising one edge off the tabletop and creating a 20° angle (40° total angle) for sharpening knife blades. The sides are elliptically shaped. There is a surface with large radius for sharpening PlainEdges and a small radius for serrations. Lay it horizontally and it creates a 12.5° angle designed for sharpening scissors. It comes packaged in a suede leather carry case that doubles as a non-skid counter top pad while sharpening. A detailed instructional DVD is also included.
