Abstract
The present invention discloses an apparatus for removing unwanted plants from a specific area of soil. The invention is comprised of a blade that is adapted to penetrate the surface of the soil and moving substantially parallel to the surface thereof. Proper movement of the blade is assisted by fins positioned on the sides of the blade, and act similarly to the rudder of a boat. The blade has a support member that has one end attached to the blade and the other end is capable of receiving a handle. The handle is configured in an arcuate shape to better facilitate grasping and holding by the user. This combination allows the user to grasp the handle, one hand on each side of the support member and blade, and push the invention forward undercutting the undesirable plant roots, thereby killing them. Minimal disruption of the soil is experienced, thereby optimizing the efficiency of work done by the user.
