Description: |
| The movable jaw is held in position by a tooth on the swinging handle that engages one of a series of serrations on the main shank. A tension spring tends to hold the handle in the closed position. The entire movable jaw structure can be slid off the main shank to facilitate the use of the hammer. The end of the handle has a socket to hold a bit or screwdriver. |
