Chef's Choice 4609700 knife sharpener- 2-Stage- Metallic

Product Description This professional quality knife sharpener combines key features essential for consistent razor-sharp edges; precision sharpening angle guides, two-stage sharpening, and 100% diamond abrasives, in an easy-to-use design that is safe for quality knives. Amazon.com Diamond abrasives in this tool actually sharpen a knife rather than simply realign its edges, as most sharpeners and sharpening steels do. For right-handers and left-handers alike, it's simplicity itself to use. Grasp the handle and draw a straight-edge blade back and forth through the stage 1 guide 25 to 50 times to coarsely bevel it. Then move the blade to the stage 2 guide and draw back and forth 10 times through finer diamond crystals for the second, fine-edged bevel. Serrated blades go only through stage 2. By turning, rollers demonstrate that a blade is properly straight so it is being beveled at the precise angle required. Lightweight but tough, the sharpener is formed of silver and black plastic. It's 6-1/2 inches by 2-1/4 inches, small enough to take on a camping or hunting trip. --Fred Brack
