  • Patent number: 4478033
    Abstract: A gardening tool having a long straight handle with a rake head on one end and a hoe head on the opposite end. The rake head has tines which extend beyond the one end of the handle at an obtuse angle to the longitudinal axis of the handle and terminate in transverse teeth which are disposed completely on one side of the handle. The hoe head extends beyond its end of the handle at an obtuse angle to the longitudinal axis of the handle and it presents a flat blade located completely on one side of the handle. The rake head and the hoe head are offset from each other rotationally about the axis of the handle to prevent the hoe head from striking a person using the tool for raking and to prevent the rake head from striking the person using the tool as a hoe.
