  • Armoring element of a knife haft for connecting to a knife blade and method for producing a knife
    Patent number: 8065942
    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.
