Abstract
An extension handle facilitating use of a handheld electrically driven grass shear from an upright standing position that removably attaches to the hand grippable portion of the grass shear by depending pairs of opposed, resilient, inwardly biased clamps. A flexible strip extends through the extension handle for remote control of the grass shear on/off controls from the hand gripped section of the extension handle. The flexible strip includes a depending cam for laterally moving an on/off slide lock switch. Inwardly directed guide posts within the extension handle direct movement of the flexible strip substantially in the direction necessary to actuate the controls on the grass shear.
