Lee Valley newsletter article on this hammer
Description:
The stepped claw was used to pull nails without bending them. During wartime, nails were scarce, which presumably motivated this patent. A Lee Valley Tools newsletter alerted us to the existence of this patent hammer; see the link under the image.
