Description:
Image and title self-explanatory. 2nd image contains: (a) a known example shown in a Facebook "Old Hand Tools" group with the paired hammer claws, and other cryptic markings. (b) another known example marked only "TAIWAN" with a single "hook" in lieu of paired hammer claws, and a rectangular poll has the poll & "hook" "reversed," so may reflect a different but similar design patent.

Term: 14 years. The patent has an extensive list of citations to "prior art."
