Abstract
A weeding tool includes a long metal handle and a metal head attached to the lower end of the handle. The head includes a metal annular, planar ring, the periphery of which includes a plurality of spaced trapezoidal teeth. The entire peripheral edge of the ring is sharpened, and the entire circular inner edge of the annular ring also is sharpened. A pair of cross-braces attach the ring to the lower end of the handle. The tubular metal member and the handle are inclined at an angle of approximately 38 degrees to the plane of the ring. In use, the annular ring is placed on a ground surface and the handle is raised or lowered to aim the front or rear portion of peripheral edge into the ground. As the front edge portion of the ring is pushed into and forward through the soil, it passes over the edge of the ring and through the opening in the ring. Roots of weeds are cut beneath the ground surface by the sharp front edge as the rear peripheral edge of the ring is pulled through the soil in the manner of using a hoe the roots of weeds are cut beneath the soil surface, and the surface soil passes over the ring and through its hole. The hole, surrounded by the annular ring, results in greatly reduced resistance to movement of the ring through the earth, and results in much less disruption of the surface layer of soil than is the case if a conventional hoe or other weeding implement is used.

Important Notes on Latency of Status data
Please note there is up to 60 days of latency in this Status indicator for certain status conditions. You can obtain up-to-date Status indicator readings by ordering PAIR for the file.
An application with the status "Published" (which means it is pending) may be recently abandoned, but not yet updated to reflect its abandoned status. However, an application filed less than one year ago is unlikely to be abandoned.
A patent with the status "Granted" may be recently expired, but not yet updated to reflect its expired status. However, it is highly unlikely a patent less than 3.5 years old would be expired.
An application with the status "Abandoned" is almost always current, but there is a small chance it was recently revived and the status not yet updated.
Important Note on Priority Date data
This priority date is an estimated earliest priority date and is purely an estimation. This date should not be taken as legal conclusion. No representations are made as to the accuracy of the date listed. Please consult a legal professional before relying on this date.
