ROTATABLY DRIVEN CUTTING KNIFE, PRODUCTION METHOD, AND KITCHEN APPLIANCE

摘要

The invention relates to a rotatably driven cutting knife (7) for a kitchen appliance (1), in particular an immersion blender (2), comprising at least one first support arm (10) that has a knife edge (14). According to the invention, the knife edge (14) is at least locally formed by a sharp edge (18) of the semifinished product (17) used for making the cutting knife (7). Preferably, two first support arms (10) are provided which are angular and have a radially internal leg and a radially external leg that comprises the knife edges (14). Furthermore, the cutting knife (7) advantageously has second support arms (15) which extend opposite each other from the center of the cutting knife (7) and are arranged on the cutting knife (7) in such a way as to be twisted relative to the first support arms (10). The invention also relates to a method for producing a cutting knife (7). In said method, at least one edge (18) of a semifinished product (17) is sharpened like a knife, and the cutting knife (7) is then cut out of the semifinished product (17) such that the respective edge (18) of the semifinished product (17) forms a knife edge (14) of the cutting knife (7). The invention finally relates to a kitchen appliance (1), in particular an immersion blender, which is fitted with such a cutting knife (7). The invention allows rotatably driven high-quality cutting knives (7) to be produced in a particularly efficient manner.
