Knife Slots

Electric sharpeners that have more than one blade slots for your knives offer multi-step sharpening process. Such is better compared to just single slotted systems because they boost the life of the unit by dealing with bluntness in a simple process. Whether it is a 2-stage or 3-stage sharpener, the sharpening process should be straightforward and require little or no learning curve.

A device with two or more stages will usually deliver razor-sharp knives better than a single slot. The multiple-stage also mean that you have an easier time sharpening your knife to the right level. For instance, a knife used for slathering butter need not be too sharp otherwise it becomes a cutting tool.

Types of Blades

Sharpeners for ceramic knives are designed for ceramic knives, but a sharpener that can also handle steel knives will be more convenient. It is also important to remember that most of the sharpeners are for flat blades. If you want to be in a position to also sharpen ceramic and steel blades, take care that your device can handle them. Not all units are designed equal so ensure that you buy a tool that will handle all knife sharpening needs you have.

Sharpening Degree

The angle through which your sharpener works will determine the kinds of results you get on different knives. Kitchen knives require between 17 to 20 degrees. Asian style knives are designed to be 15 degrees. You may consider a sharpener that can handle both angles so you can enjoy fine cut knives even as time passes by. It is best you know about the angle of sharpening before buying your device.

But for the electric ceramic knife sharpener, everything is taking care of.

Sharpener Material

Durability is very important, even when buying an electric knife sharpener for your ceramic knives. Units that have diamond abrasives are far more durable considering that diamond is among the hardest minerals on earth. Devices featuring diamond in their design may be a little pricey compared to others, but they are definitely worth it. As for sharpeners for ceramic knives, only diamond abrasives are used.

Ease of Cleaning

Remember that the sharpening process means dust resides because parts of the blade are shaved off to achieve the sharpness. Consider therefore how the metal or ceramic shards are collected at the unit and whether it is possible to separate the parts for easy thorough cleaning.

Design and Size

Design and size of sharpeners are usually a matter of personal preference. Consider where you wish to place the sharpener when looking at size and design. Also, remember that larger units may come with more features compared to compact units. Know your needs clearly, make comparisons and select the device that appeals to you the most. Most people will look for a powerful and compact unit. The Kyocerca knife sharpener is a battery operated device, so it’s portable and compact.
