| Description: |  | Ball-pein hammer with a knurled metal handle; the design seems to show parting lines, so the design may reflect a hammer with nested screwdrivers in the handle. Edelmann received British patent GB-142,008 and Canadian patent CA-216,934 for a hammer with nested screwdrivers stored within its hollow handle. My childhood home "junk drawer" included one of these lightweight tools. |  |
