A foldable shovel structured for scooping/pushing is provided. The disclosed foldable shovel includes two arcuate members that are hinged together at one end. In the folded configuration the two arcuate members are nested. Further, the coupling device includes a locking disk assembly structured to allow the arcuate members to be configured in different positions relative to each other. Thus, the foldable shovel may be optimally configured as either a scooping device or a pushing device.
