ABSTRACT:
A silicone paint brush artist's tool includes a handle and a novel painting tip. The painting tip is made of a resilient silicone having a generally three-dimensional paint contacting working surface that has a maximum cross-sectional diameter no larger than a maximum cross-sectional diameter of the handle. The tip is preferably attached to the handle using a ferrule and expansively locking the tip into a cavity of the ferrule by insertion of an insert. The insert may be a common screw or a barbed, fluted extension of the handle. The tips may include an insert cavity and have various shapes and hardnesses and may be optionally color coded. A formation method for the tool is disclosed with simultaneous insert insertion and joining of ferrules to handles. The ferrules also may be reversibly attached to the handle, in which case a kit comprising multiple interchangeable painting tips may be provided.
