  • Patent number: 4681150
    Abstract: Elongate grooves are provided along both or one side of the shank of a knitting needle. The elongate groove is parallel with the back edge and is positioned between the back and front edges of the shank of the needle. The elongate grooves reduce the weight of the needle without substantially reducing the vertical rigidity of the shank of the needle and function to reduce the transmission of impact shock from the needle butt to the hook. The grooves also provide a passageway extending longitudinally along the needle shank to provide for improved retention and distribution of lubricant along the needle shank.
