Abstract:
1. A combination utility and sporting knife, comprising: a longitudinal knife handle; a utility blade carrier disposed within said handle and linearly movable within said handle; a utility blade carried by said blade carrier, said utility blade having a trapezoidal shape, a longest side of which comprises a linear cutting edge; a manually movable blade moving member operatively connected with said blade carrier and disposed towards an upper portion of said handle, said blade moving member being linearly movable between 1) a first position wherein said utility blade carrier and said blade carried thereby are positioned so that said utility blade is in a storage position wherein said cutting edge thereof is confined within said handle, and 2) a second position wherein said utility blade carrier and said blade carried thereby are positioned so that said utility blade is in an operative position wherein said cutting edge thereof extends outwardly from said handle; a pivotally movable sporting blade pivotally connected to said handle, said pivotally movable sporting blade comprising a cutting edge and an opposite dull edge, said cutting edge having a convex forward portion, said convex forward portion of said cutting edge intersecting with said dull edge to form a forward point of said pivotally movable sporting blade, said pivotally movable sporting blade being movable between a storage position wherein said cutting edge thereof is concealed by said handle and an operative position wherein said cutting edge is exposed, said utility blade and said pivotally movable sporting blade being extendable from opposite ends of said handle, a blade release structure operable to enable said utility blade to be selectively released from said blade carrier so that a replacement utility blade may be carried by said blade carrier, wherein the utility blade carrier, the utility blade, and the manually movable blade moving member constitute a utility blade assembly; and a blade interlock constructed to interact with the utility blade assembly and pivotally movable sporting blade to prevent movement of one of the utility blade and the pivotally movable sporting blade from the storage position thereof when the other of the utility blade and the pivotally movable sporting blade is in the operative position thereof.
