How to Sharpen Electric Knife Blades

How to Sharpen

The first step is to clean your knife blade if you have been using it or if it has some/any residue. Such dirt can interfere with the sharpening process so make sure the blade is clean.

As mentioned earlier, sharpening using an electric sharpener such as the Chef’s Choice M120 is the best way to go.

Note: Most electric knife blades are serrated therefore make sure that the electric knife sharpener is able to sharpen such a blade.

However, this is not the only way to sharpen blade. You can always use the traditional sharpening rod which is slower and more strenuous. Nevertheless, it gets the job done. To sharpen with a rod, place the rod within the first serration – this is the first serration on the blunt end you are holding it from.

Next, begin sliding the electric knife blade gently back and forth on the sharpening rod. Remember to have the sharpening rod placed in the same direction as the serration on the blade. Slowly work your way to the outermost serration at the tip of the electric blade.

All that’s left is to sharpen the opposite edge of the blade remembering to place the rod in the same direction as the serrations. That’s all it takes to sharpen an electric knife blade using a sharpening rod.
