Some of these hammers (nos. 64-65) belong to various artisans and professionals, including archaeologists, orthopaedists, astronauts, carpenters, upholsterers, locksmiths, soldiers, firefighters, longshoremen, roofers, shoemakers, watchmakers, etc. and are intended for one specific purpose. Others are invented hammers that have no purpose, but are nonetheless usable.
