  • Patent number: 5564267
    Abstract: A tool formed by a pivotal connection between a first shaft and a second shaft. One shaft has a scooping head such as a shovel or a rake head. The other shaft has a rake head with a plurality of tines having bent distal end portions extending out in a direction away from the scooping head. The rake head may further include flanged portions extending from the distal end of the rake head in a direction toward the scooping head. The pivotal connection may be designed so that it is detachable; and, if so, detachment may be limited to when the shafts are separated in a maximum full open position. The combination tool may be used for raking and picking up leaves or other debris.
