Abstract: A cordless electric lawn edger utilizes a flexible strand of nylon monofilament rotated at high speed to effect cutting of grass and weeds. The rotating assembly mounting the strand is substantially conical in order to reduce drag and prevent grass from wrapping around the assembly. The strand is fixedly secured within a detachable and disposable tip member which easily snapfits into a rotatable truncated cone member. The cone member is, in turn, secured to the drive shaft of a DC motor. The edger is provided with both a grip handle and a loop handle arranged for optimum tool balance and handling.

Abstract: A cordless electric device has an external side pocket for receiving a battery pack power source. The battery pack includes a pair of standard AC prongs projecting from one flat sidewall. The prongs may be received by a set of openings in the device pocket for powering the tool or may be inserted into an ordinary AC household receptacle for charging the batteries. A spring-loaded switch located on the same pack sidewall has a first normal position for connecting the batteries to a rectifier for charging and a second actuated position for connecting the batteries directly to the prongs for powering the device. The device is provided with a manually operable mechanism for contacting the spring-loaded switch in the pack and thereby switching the pack from a charge to a discharge mode. In a specific embodiment, the actuating mechanism comprises a trigger mounted on a pistol-type soldering gun.
