Abstract

A pair of grass shears includes a base blade having a handle secured to one end, and a movable blade rotatably secured to the base blade. A follower is rotatably received in the handle and has an eccentric shaft slidably engaged in a slot of the movable blade. The movable blade may be rotated relative to the base blade when the follower is rotated to move the eccentric shaft along the slot of the movable blade. Two gears are rotatably received in the handle and engaged with each other. One of the gears is secured to the follower. The other gear may be coupled to and driven by the power tool.
