An apparatus for gripping hot investment molds either of the ring type or of the oval type, has a plastic handle with an elongated square tube extending therefrom. A trigger in the handle is connected to a linkage rod which pulls back on a closer frame. Rearwardly extending crossed tails of a pair of jaws are squeezed together by rearward movement of the closer, for closing outwardly extending palms of the jaws around an investment mold. The jaw assembly is removable so that jaws having shapes adapted specifically to engage either an investment ring or an investment oval can be provided.
