#8. SANKOO 2-Stage Multi-Angle Kitchen Knives Sharpeners
By: Sankoo
Sankoo knife sharpener is an electric knife sharpener. This type of sharpener distinguishes the very easy operation and handling. The diamond-coated grinding wheels of the sharpener ensure minimal material removal on the knife blade. The blade receives the so-called “bow-shaped cut” which is known for its precise sharpness and durability. Diamond is the hardest of all gems. So you can gently, quickly, and optimally grind the knives. A softening of the material due to overheating is excluded.
With the dimensions of 25cm in length, 11.2cm in width, and a height of 11cm, it is also in the size of the more bulky devices that you use to sharpen the knife. If the device is too bulky in shape and size, you should opt for a grindstone or sharpening steel. Specifically, this means that this knife sharpener is more suitable for kitchen cabinets than for the drawer. Compared to other knife sharpeners, the machine is significantly bulkier and less flexible. Nevertheless, the device does not take away a lot of space and will certainly find a suitable place in a smaller kitchen.

#5. EdgeKeeper Electric Knife Sharpener, Red
By: EdgeKeeper
The EdgeKeeper knife sharpener is a professional tool in the field of knife sharpeners. Sharpening with a belt sander, as practiced by many professional knife makers, combines the comfort and speed of an electric sharpener.
Unfortunately, the EdgeKeeper knife sharpener loses its optical criteria in contrast to grindstones and what sticks. With the typical workshop look, the device is reminiscent of a real machine rather than a filigree device. The device is only available in black, but with this type of knife sharpener, you should not have much influence on the purchase decision. In principle, it is about the result and the functions of the sharpener and not about a beauty award.
