Abstract: A bivalve shell opening blade is fixed by an end to a handle and has a pointed, oppositely disposed free end extending forwardly therefrom. The blade is angularly disposed to the handle so as to fall in aligned continuation of the user's forearm when grasping the handle with free pointed end forward. The blade is offset from the handle for increasing hand leverage in opening the bivalve shells, and the angular disposition of the blade in alignment with the forearm maximizes blade point insertion force between shells and minimizes hand to handle friction and reduce muscular fatigue and blisters in use.
