The Edge Craft knife sharpener uses 100% diamond abrasives, the world's hardest known material. This enables sharpening of any alloy metal faster and more efficiently without ever ruining the temper of your edge. The Diamond surface keeps the sharpening surface cooler than other materials can, so as to not harm the knife. Our patented, flexible spring knife guides ensure precise angle control and eliminate guesswork. This multi-stage design both sharpens the edge and then hones it to a razor sharp finish. This sharpener can also sharpen serrated blade knives. Ideal for pocket, fillet, kitchen and household knives.
