Abstract: A knife includes a knife blade having a tang and an RFID transponder which is fixed to the tang. A knife handle surrounds the tang and the RFID transponder. The knife blade is produced from metal, in particular steel. The RFID transponder has an antenna and at least a portion of the antenna of the RFID transponder is constructed in a planar manner and is arranged parallel with a planar lateral face of the tang. In another embodiment, the antenna of the RFID transponder is galvanically connected to the tang. The knife having the RFID transponder increases the reliability of the reading by an RFID reading device.

Abstract: A sharpening device 1 for knife blades comprising a base plate 2 with a guiding slot 6, designed as an incision in the base plate 2, for a knife blade to be sharpened and sharpening rods 10a, 10b disposed on both sides of the guiding slot 6 to be pivotable against an elastically resilient restoring force, wherein the guiding rods 10a, 10b intersect at a point of intersection 11 in the area of the guiding slot 6. At least one of the two walls of the base plate 2, which are disposed opposite to each other and form the guiding slot 6, thereby forms a knife abutment surface 7a, 7b and at least one magnet 20, 21, 22 is mounted to the base plate 2 in the area of the knife abutment surface 7a, 7b.

Abstract: The invention comprises an armoring element (1) of a knife haft, which has a bar (10) extending in an axial direction (100) and is connected to the tang (20) of a knife blade (2) using a connecting means (11). A secure, frictional connection in an axial direction (100) between the armoring element (1) and the knife blade (2) is formed by positive locking and/or material bonding between the connecting means (11) of the armoring element (1) and a corresponding counter piece (21) on the tang (20) of the knife blade (2). In an inventive method for producing a knife, the tang (20) and the armoring element (1) are coated with haft material, e.g. haft shells in the connected state. The haft material forms the actual body of the knife haft, wherein parts of the surface of the armoring element (1) may be disposed in the outer surface of the knife haft such that they are visible.

Abstract: A sharpening device (1) with a guiding slot (6) for knife blade to be sharpened and main sharpening rods (10a, 10b) arranged on both sides of the guiding slot (6) that cross each other at a crossing point (11) in the area of the guiding slot (6) and that execute pivoting movements (14a, 14b) against an elastic spring-activated resetting force when a knife blade abuts against them, is additionally equipped with pre-sharpening elements (7a, 7b) in at least one longitudinal segment of the guiding slot (6). During its course along the guiding slot, a knife blade to be sharpened abuts against the fixed pre-sharpening elements (7a, 7b) and against the movable main sharpening rods (10a, 10b) whereby the sharpening effect of the sharpening device (1) on the knife blade is increased.
