Electric knife sharpeners do most of the work for you. You just need to put the knife in the sharpener and slowly slide it to touch up on the entire length of the blade. The precision guidance system will help to make sure your knives get sharpened directly on the blade, taking the worry of ruining your blades away. The electric sharpener has a replaceable grind wheel, so after the original has worn down, you can simply replace the wheel rather than replacing the entire unit. The housing if this unit is made of stainless steel, ensuring that the sharpener will look good even after many uses. The knife sharpener can also manage scalloped blades, so when your bread knife starts to wear, you can sharpen them too. - Stainless Steel - Sold Per Each
