We tried a lot of sharpeners before settling on this one. it is available in many colors and finishes but the key is having three slots that start with a coarse grinder on the left and finish with a smooth diamond pad on the right. The spring loaded bevel guide holds the knife at exactly the right angle. The diamond hones impart a perfect edge. Sharpening is safe, fast and easy. The many other devices we have tried just do not work for us. We love this product and if we cook at your house and like you a lot chances are good Santa will get you one.
