This trenching tool, or shovel, was designed with an adjustable angle blade. Used by the astronauts on the Apollo 14 mission to make trenches in the lunar soil, the stainless steel trenching tool was replaced by adjustable angle scoops on later flights.
This particular shovel was used for training exercises. It was transferred from NASA to the Smithsonian in May 1974.
