Abstract
A shearing tool has two blades which are pivoted together by a pivot in conjunction with a nut. The pivot has a head, and a shank which is provided with a lubricant cell and plural channels. The lubricant cell is in communication with the exterior of the shank area, the channels enabling the lubricant contained in the lubricant cell to lubricant the two blades. The lubricant cell includes a depressed oiling region for containing oil therein during re-lubrication. The shank has outer threads to mesh with inner threads of the nut.
