A weed extraction tool is disclosed, comprising an elongated handle, a prong assembly, and a step assembly. The prong assembly includes a rod having a plurality of prongs attached at a lower end thereof and a pivot pin holder near its center. The step assembly comprises a flat step portion at one end, a plurality of fingers at another end, and two sides near the center of and under the step assembly. An opening is formed in the top side proximate its center, and each side includes a side opening. The rod of the prong assembly is inserted through the opening in the top side of the step assembly such that a pivot pin may be inserted through one side of the step assembly, through the pivot pin holder, and through the other side of the step assembly, so as to pivotably fix the prong assembly to the step assembly. As such, the opening of the top side of the step assembly is sufficient only to allow the step assembly to pivot between closed and open positions with respect to the prong assembly. In the open position the user may step on the step assembly to burry the prongs into a portion of ground adjacent to a weed. Then, while the handle is pulled towards the user, pivoting the step assembly around its contact point with the ground, the step assembly is forced into its closed position with respect to the prong assembly, the fingers pressing the weed against the prongs so as to firmly hold the weed therebetween while the handle is pulled towards the user to fully remove the weed from the ground.

What is claim is: 1. A weed extraction tool, comprising; an elongated handle including at a lower end thereof a threaded receptacle aligned co-axially with the handle; a prong assembly, comprising a rod having at a lower end thereof a plurality of prongs, a threaded portion of the rod at an upper end thereof adapted to cooperate with the threaded receptacle of the elongated handle, and a pivot pin holder fixed between the upper and lower ends of the rod and mounted transversely to the axis of the rod, the pivot pin holder adapted for holding a pivot pin; a step assembly, comprising a step portion at one end thereof, a plurality of fingers at another end thereof, an opening in a top side thereof between the one and another ends thereof for receiving the rod of the prong assembly therethrough, and an opening in a side thereof between the one and another ends thereof for holding the pivot pin; whereby, with the rod of the prong assembly positioned through the opening in the top side of the step assembly, the pivot pin may be inserted through the openings in one of the sides of the step assembly, through the pivot pin holder of the prong assembly, through the other of the sides of the step assembly, and retained with a cotter pin, such that the prong assembly is pivotably retained by the prong assembly, the threaded portion of the rod engaged in the threaded receptacle of the handle with the rod and the handle aligned co-axially. 2. The weed extraction tool of claim 1 wherein the elongated handle includes an elastomeric hand grip fixed at a top end thereof. 3. The weed extraction tool of claim 2 wherein the top end of the elongated handle forms an angle β with respect to the rest of the elongated handle, the angle β being approximately 135째. 4. The weed extraction tool of claim 1 wherein the step portion of the step assembly further includes a flange at a distal end thereof, the flange angled away from a top side thereof. 5. The weed extraction tool of claim 1 wherein the prongs of the prong assembly form an angle α with respect to the rod of the prong assembly, the angle α being approximately 135째. 6. The weed extraction tool of claim 1 wherein the plurality of prongs comprises a pair of prongs. 7. The weed extraction tool of claim 1 wherein the plurality of prongs form a V-shape such that roots of a weed maybe wedged between the prongs and held firmly to facilitate the extraction of the weed from a portion of ground. 8. The weed extraction tool of claim 1 wherein the plurality of fingers comprises three fingers, such that the fingers can interlace with the prongs. 9. The weed extraction tool of claim 1 wherein the opening in the top side of the step assembly is elongated and of such a size as to allow pivoting of the step assembly only between approximately ten degrees and ninety degrees with respect to the prongs.
