  • Patent number: 4610086
    Abstract: A hand tool for sheet metal workers notches and soft-noses an end of a sheet metal drive in one operation, and saves time and prevents injuries as compared with use of tin snips to do the same job. Paired handles of the tool are held in one hand while, with the other hand, the end of a sheet metal drive is slid onto an upper plate and against a stop. The upper plate, a lower plate fixed to it, and a blade shaped to engage portions of the periphery of the upper and lower plates form a shear in which a lower plate fixed in parallel spaced relation to the upper plate serves to support a portion of the drive. Shape of the shear causes the drive to be notched and soft-nosed with a squeeze of the handles.
