Abstract
Abstract This gardener's hand tool has a double-ended head at one end of a handle. One end edge of the head is beveled to form a cutting hoe-like blade and the other end is provided with spaced tines which are rounded in cross-section to form tapered wedge-shaped recesses for receiving and pulling weeds and roots. The handle is rigidly secured to the head and the latter is bent at two places to dispose the cutting blade and tines at a critical angle relative to the handle to secure the most efficient operation of the tool. A unique connection between the head and handle prevents the rotation in and/or separation of the latter from the head.
