A rake for smoothing sand and other particulate material surfaces has a head which is an elongate helical coil. Preferably, the coil is a coil spring which can be compressed axially from an open to a storage condition and means are provided for retaining the spring in its storage condition and advantageously also in intermediate operative conditions to compensate for variations in coarseness of the particulate material to be raked. It is also preferred that the rake handle is formed of a mutually inclined pair of arms movable to reduce their included angle and having the coil spring extending between their distal ends. It is especially preferred that the arms are arcuately mutually divergent so that the distal ends thereof move substantially linearly.
