      Striking a hand-held isotropic block or cobble (a core) with a hammerstone initiates a cone-shaped crack at roughly 60° from the axis of force, exemplified by the hole in a plate glass window made by a pellet gun (18, 19 ).
    • 1905, Andrew Lang, The Clyde Mystery[2]:
      On the other hand, in the same crannog, a hammerstone broken in two was found, each half in a different place, as were two parts of a figurine at Dumbuck.
