The Apollo astronauts were provided a small rake that could be used to gather and collect pebbles larger than 1 cm in diameter from the lunar regolith. The rake head (this object) was attached to a handle, which while on the lunar surface was designed to attach to a standard extension handle. Lunar rakes were employed on Apollo 15-17, from July 1971 to December 1972. This artifact was used for training.
This was transferred to the Museum in 1978 from NASA.
