The unique design of the CRKT Veff Sharp Tool allows it to sharpen pretty much anything. The kit includes two 600 grit, diamond coated sharpening rods that can be attached to the threaded aluminum handle on either end. The smaller rod consists of three, two inch sections of 332, 316, and 14 inch width rods, while the larger rod is equipped with 1132, 12, and 58 inch width rods along with a six inch section with a flat back. All of these differing widths give the tool the ability to sharpen both standard and Veff serations, and the flat back can be used as either a file or bench tool when sharpening straight edges. The Veff Sharp Tool can also be used to sharpen chainsaw teeth, pruners, fish hooks, and box cutters.
