Abstract: In a knife sharpener with two whetting disks (2, 3) which are rotatably mounted about the same axis of rotation (8), oppose each other and have whetting surfaces (11, 12) facing each other, which between themselves form a sharpening slot (13) which widens outwards in radial direction, and with a housing (4) which surrounds the whetting disks (2, 3) and above the sharpening slot (13) includes a knife guiding slot (24) which extends at an angle (?) to the sharpening slot (13), at least a first one of the whetting surfaces (11) is formed convex and the second whetting surface (12) is formed linear or likewise convex in radial direction.

Abstract: In a sharpening rod with a peripheral surface which constitutes a sharpening surface, wherein the sharpening rod (1) is formed of a material with specified grain size, the peripheral surface includes at least two pairs (2, 3) of sharpening surfaces (2a, 2b, 3a, 3b) of different materials, which sharpening surfaces of each pair are located opposite each other transverse to the longitudinal direction of the rod, wherein the pairs (2, 3) of sharpening surfaces are arranged offset with respect to each other in peripheral direction of the sharpening rod (1) and a first one (2) of the pairs (2, 3) of sharpening surfaces is formed of a first material with a first grain size and the at least second pair (3) of sharpening surfaces is formed of a second material with a second grain size. Furthermore, there is proposed a method for manufacturing such sharpening rod (1).

Abstract: The inventive nail clippers comprise a two-membered clipper body (2) with a metal fitting (8) placed inside. The metal fitting has a U-shaped spring section (46) that, at the end of each of its legs (48), has bent portions (50) which form the cutting edges (10). The two clipper body members (4,6) also have angled portions (64,66) which encompass the leg ends of the spring section and which meet together opposite to the bent portions (50) that form the cutting edges (10). The angled portions engage with each other in such a way that they fit together, thereby ensuring that the cutting edges are accurately guided when they meet, even when the clipper body is made of plastic and is thus relatively resilient.

Abstract: A nail clipping apparatus designed to overcome the drawbacks of the prior art. Synthetic nail clippers are easier to manufacture and much more cost-effective than metallic clippers. However, synthetic clippers often produce results that are unsatisfying due to the flexible nature of synthetic materials. Such unsatisfactory performance can result in injury and imprecise cutting. This invention has undertaken to remedy the shortcomings of the prior art and to provide an economical synthetic clipper body with separate metallic cutting portions, along with a catch-lock mechanism and several alignment components that result in a newer nail clipping apparatus which is both precise and cost-effective.
