TWIN Sharp

There are several methods and utensils of sharpening, each having its advantages and disadvantages.

Mainly, we have the classic methods of sharpening the knife on the stone or with the help of the sharpening file. 

But there are also new sharpening devices which also use the same basic principle (namely the friction of the knife blade with another hard material: stone, steel, diamond, ceramic, glass, etc.).

Ideally, the sharpening is carried out starting with the harshest instrument (stone, etc.), with the highest granulation and ending with the instrument that has the finest granulation.

There are hundreds of devices for sharpening but few of them are truly effective. Many of these fall into the category of gadgets. And here you have to choose between the manufacturers, the most famous using high-performance materials for manufacturing these products.
