  • Patent number: 6245977
    Abstract: A plectrum having a pair of contact points for double striking the strings to achieve a fuller sound. The plectrum having a pair of contact points includes a panel. The panel has substantially planar front and back surfaces. The panel has a top edge and two side edges. The side edges taper to an outer point positioned distal of the top edge. The panel has a proximal portion adjacent to the top edge and a distal portion adjacent to the outer point. A slit is in the distal portion. The slit is pointed and has two legs extending away from a point of the slit. The point of the slit is located generally adjacent to the outer point defined by the two side edges. The legs of the slit extend toward the proximal portion. An inner point of the distal portion is defined by the slit. The outer and inner points both strike the strings of an instrument when the plectrum is brought across the strings.
