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.
Claims3
A bivalve shellfish opening knife comprising:
- (a) an elongated handle means having oppositely disposed ends for hand grasping therebetween;
- (b) a straight blade means extending downwardly and forwardly, and having a free pointed end for forced insertion between said shellfish bivalve shells by, and in line with, a user's operating forearm, wrist and hand, and having oppositely disposed and spaced apart sharp edges that in side to side rotation is for opening said bivalve shells, and in forward and rearward motion for cutting said shellfish free from said shells;
- and
- (c) connecting means integral with said blade means for fixing said blade means to said handle means, with said blade means being linearly offset forward from said handle means and aligned with said user's operating forearm, wrist and hand, and with both offset and alignment being in a common vertical plane for the linear application of all insertion force to penetrate between said shells of said shellfish, and for the increased leverage and efficiency resulting therefrom.
