Application: cutting instruments.

The problem to be solved: to provide maximum prevention of the adhesion of products to be cut onto the side surfaces of the knife and improvement of cutting conditions and properties of cut product pieces in the account of maximum minimizing of the contacting area between the knife blade and cut product keeping the plane of cutting and expedite ingress of the air into the cutting area.

Essence of Utility Model: in the knife for the cutting of wet and/or adherent products that has the handle and the blade with the cutting edge, the blade is made in a form of elongate hollow frame or its part. The blade is provided with at least one protruding long part, and the frame hollow is filled up with non-metallic material. The knife having such blade combines the properties of metallic materials, such as hardness and strength, and the properties of some non-metallic materials – low density (in comparison with metals), low adhesion towards many food products, and, the main thing, ample opportunities for design: easy forming, combination of materials of various colours, texture and degree of transparence.
