Description: |
| Light weight "ball pein" hammer with multiple size nested screwdrivers stored in the handle. Corresponds to British patent GB-142,008 and U.S. Design patent D54,162.
Produced as Edelmann's "HAN-D" hammer. The arrangement of the screwdrivers resembles Edelmann's earlier 4-in-1 screwdriver (where the two smallest sizes are "loose" inside the next larger size), and one form of the "Three--in-One" screwdriver.
Edelmann also used an alternate arrangement for nested screwdrivers based on 1917 patent no. 1,250,328. |
