ABSTRACT:
A gardening tool for cutting weeds and other plant growth having a handle and a cutting head comprising first and second blade members which are adjustably positionable relative to each other. Each blade member has an elongated body having cutting edges extending along opposite longitudinal sides thereof. The blade members are connected end to end by a carriage bolt which is received by apertures in a first end of each blade member. The aperture in the first blade member is complimentary in shape to the square shank portion of the carriage bolt. The aperture in the second blade member is a star-shaped polygon which defines a plurality of contact surfaces for engagement with the square shank portion of the carriage bolt. When the second blade member is positioned on the first blade member at the desired angular orientation relative thereto, it will resist rotation due to the interengagement of the apertures with the square shank portion of the carriage bolt. The first blade member is bolted to a terminal end segment of the handle shaft. The terminal end segment is at an angle to the handle shaft such that the cutting head will extend substantially parallel to the ground when a standing operator grasps the hand grip portion of the handle.
