Abstract
A stick for a violin or similar stringed instrument bow is made of a first body of injection molded plastic and a second body of a different strengthening material integrally fixed to the plastic body. The strengthening material or second body is designed for placement in a mold cavity prior to the injection of the plastic material of the first body, the plastic material upon injection engulfing the second body and filling the remaining empty space of the cavity to integrally fix the second body to the plastic body and to form a unitary finished bow stick. The combination of the two bodies provides a finished bow stick having weight, stiffness and other characteristics similar to that of a conventional wooden stick.
