AN IMPROVED ACCURATE LIGHTWEIGHT MANUAL LAWN AND GRADE WEED CHIPPER ABSTRACT An improved accurate lightweight manual tool to cut suburban lawn and garden weeds efficiently and with little time and effort expended. It is like a miniature hoe half a man's height in length with a very thin very narrow blade (E), in length four to five times its width (FIG. lb). The chipper's light weight is achieved with a very lightweight conduit handle (A) of any section joined at right angles to (D) a backing plate for the blade (F) and weighted with billet (G) to increase and change the power for weight. A thin shock absorber (X) may be bolted between plate and blade by (F). The joint uses a steel billet (G) driven through the metal plate (D) into the conduit handle (A) thereby expanding the handle (A) against the metal collar (C) and plate(D) which has a self-centering protrusion which abuts with a bevelled surface of collar (C). The permanent right angle locking joint uses totally prefinished components.
