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.
