This tool is an upholstery tack hammer. On one end, one side has a traditional hammer head with the opposite end having a smaller tack hammer head. Across the long handle are the welded letters “ALASKA”. The butt end of the tool is a tack puller.
An upholstery hammer is a lightweight hammer used for securing upholstery fabric to furniture frames using tacks or small nails. Many styles have two faces, one face usually being magnetized to aid in placement of tacks (Smith Tavern’s tool does not appear to be magnetized). Once started, the tacks are driven with the other face.
Staple guns largely replaced tacking as an upholstery technique.
