  • Patent number: 5297340
    Abstract: A parting tool for parting seams and/or cutting threads or the like is disclosed. The parting tool may include an arc-shaped blade located between two tines of unequal length to effect a cut. The long tine may have a thorn-like point and the short tine may have a spherical thickening above the blade. The tines pass over into a shaft, which is fastened to one end of a shaft holder or mounting. The shaft mounting may include at its other end a pressure surface oriented perpendicularly to the blade and a rotation axle located at a defined distance in front of the pressure surface and oriented perpendicularly to the blade. The rotation axle may be rotatably supported in the lateral surfaces of a casing open within the rotation range of the shaft holder. A stop is provided within the casing for the shaft of the parting tool in the swivelled in, rest position. The stop may be a spring elastic element.
