  • Patent number: 6827153
    Abstract: A garden tool with a non-slip handle grip, designed for immediate and not difficult removal of deep-rooted plants such as Thistle and Dock weeds. The body of the tool is of rigid and strong construction, with angled cutting faces and includes a plant/soil containment chamber. The tools angular cutting faces and profile, are designed to produce efficient insertion and soil compression when downward thrust is applied, which therefore holds captive the plant root in the containment chamber, hence achieving successful plant removal from the ground when the tool is withdrawn. The slotted front of the containment chamber allows for unwanted plant and soil removal from the tool. Optional hand and foot cross-members added, to produce more forceful insertion into and easier withdrawal from the ground, and to create a convenient standing operating stance, when using the tool.
