| Abstract: |
A hand tool used to manage and cultivate soil in confined areas, as planters and pots, for growing plants. The tool has an elongated handle having an end integral with an earthworking implement. The handle has triangularly related linear sides which taper inwardly toward the earthworking implement, wherein the sides are adapted to be engaged by the first and second fingers and thumb of the user. On the end of the handle opposite to the earthworking implement, the sides converge into a cylindrical section terminating in a knob. The earthworking implement includes a body having a plurality of teeth. The body can be in the shape of a shovel, pick or rake.
