  • Patent number: 9754564
    Abstract: An improved stringed instrument pick having a two-piece configuration including a holding device having a finger hole associated therewith and a pick member selectively engageable with the holding device, the pick member having a first playing surface and a second playing surface joined together at a joinder edge so as to form a V-shaped configuration. The first and second playing surfaces include first and second prong members respectively for engaging corresponding slots associated with the holding device. The pick member is selectively engageable with the holding device such that a user can use a differently angled or sized pick member with the same holding device depending upon the particular stringed instrument being played and/or to achieve a particular style or sound. As such, the present pick provides multiple playing surfaces which can be utilized in a wide variety of different ways to play a particular stringed instrument.

  • Publication number: 20160192810
    Abstract: A free floating spirally shaped mixing blade for use in a mixing chamber for mixing various substances including an elongated blade member formed so as to extend from a first end portion to a second end portion in a spiral configuration, the blade member being positionable so as to be wholly contained within a mixing chamber and free floating therein when the mixing chamber is agitated. In various embodiments, the mixing blade may include a slit positioned at an intermediate location along the length of the blade member dividing the blade member into first and second blade portions, the slit extending partially along the width of the elongated blade, and/or a plurality of openings extending through the blade member for increasing turbulence when the blade is agitated within a mixing chamber. In some embodiments, the mixing blade may take the form of an elliptical helix or a circular helix.
