This is a sanshin pick developed by Mr. Niizato of Sanshin Urumaya. It features tips (apex) with different angles, allowing users to switch between them according to the speed of the Okinawan sanshin song. The tips range from acute angles (for example, for slow songs like "Nasake Uta" around 60 bpm) to obtuse angles (for example, for upbeat songs like "Kachāshī" around 140 bpm), enabling this single pick to accommodate a variety of tempos. It produces clear, crisp sounds for "Nasake Uta" and allows for fast playing without catching on the strings for "Kachāshī." Size: Length 50mm, Width 37mm, Thickness 10mm Material: Acrylic Color: Transparent If you'd like to hear the sound, search on YouTube for "Urumaya" and "pick" to find examples.
