Best Electric Knife Sharpeners

We don’t use one single kitchen knife for food prep tasks around the kitchen. There are different types of kitchen knives, each with their own functions. Now, with knives, dull blades should be taken care of ASAP. You can always hone them manually, but if you are after convenience, the workings of an electric knife sharpener will make maintenance a simpler task to finish.

Maybe you have considered owning one but you have no idea where to begin. Here is our handy list of information on electric knife sharpeners plus the hottest products in the market at the moment.

Buyers Guide

  1. How do you use an electric knife sharpener?

    Answer: First, you need to position the knife blade in the provided slot. Press the heel of the knife down, as far as you can to connect the item with the grinding stone. Begin with the heel and tug bit by bit until it reaches the tip. Slip the knife on the slot at a 15-20-degree angle. The sharpener will set the knife handle’s angle mechanically as it gets pulled into the slot and joins the grinding stone. Pass the blade through bit by bit on every side, twice. Repeat the procedure on the finer grinding stones. Rinse the knife and allow to dry with a clean towel or rag.

  2. Can an electric knife sharpener hone all knives?

    Answer: The electric knife sharpener cannot accommodate knives with a French style and bigger metal bolsters. These metal bolsters do not fit in most electric knife sharpeners and even manual knife sharpening devices. Brands will also state the types of knives that won’t suit their sharpeners.

  3. How do you maintain an electric knife sharpener?

    Answer: Due to usage, electric knife sharpeners are prone to metal dust buildup on its grinding wheels and body. Check the area under the wheels at the back of the device and you will see a detachable drawer in there. Take away the drawer and wipe it off well using a moist paper towel or rag. This will take away metal dust buildup. To clean the sharpener, make sure that it is switched on. Push the small lever and hold for a few seconds. Next, press the lever in the opposite direction for a few seconds. This will clean the dressing tool and reshape the most-used surface of the machine. Do not use any grease or lube to clean moving components like the bearings, engines and the like. You can clean the device’s exteriors using damp towels or rags.
