Features/Specifications
This knife sharpener makes keeping your kitchen knives in tip top condition easy and simple. Simply place the sharpener on a table top and hold steady via the ergonomically designed handle then pull the knife from the back of the blade to the point in one clean motion. Repeat this up to 6 times and your knives will be back to their best.
Each section of the knife sharpener is deigned to help you sharpen various knife types such as metal and ceramic. If you have a particularly poor metal knife you can fix it by using the full 3 stages of sharpening. First use the Diamond Rods, then move to the Tungsten Steel Rods and finish with the Ceramic Rods!
