The Greenable knife sharpener made a very good impression in our test. The product itself is made of steel with a chrome-plated sharpening surface with a hardness of 65 HRC. The wooden handle rounds off the design. It is also very easy to handle and can be used by anyone. The stainless steel finger guard protects the fingers and the wooden handle sits comfortably and securely in the hand. The knife blade is pulled over the sharpening steel with light pressure along the entire length of the knife. Each side of the knife should be drawn over the sharpening steel at least three times.
Nevertheless, contact information, such as a telephone number or e-mail address, would have been desirable.

We really liked the Greenable knife sharpener in our test. It is very easy to use and can be carried out by anyone. The first positive thing we noticed was the knife sharpener’s secure stand.
To sharpen the knives, the handle of the sharpening steel is taken in the hand and held away from the body. With light pressure, the knife blade is drawn over the sharpening steel at an angle of 15-20° over the entire length of the knife.
Each side of the knife should be passed over the sharpener at least three times. In between, the degree of sharpness already achieved should be checked.
The stainless steel finger guard protects the fingers and the wooden handle sits comfortably and securely in the hand.
After sharpening the knives, the sharpening steel is wiped clean with the cleaning cloth supplied. This cloth is also used to clean the sharpened knives. It is important that all steel residue is removed from the knife.
