A set of jaw pieces comprising at least two separate jaw pieces for use in a vice arrangement is provided in which the individual jaw pieces can move between a release position in which a work piece may be selectively inserted or removed and an operative position in which the work piece is securely held between at least two of the jaw pieces, each of the jaw pieces is provided with a flange or groove for interlocking with a complementary flange or groove of another jaw piece to facilitate relative movement of the jaw pieces when moving between the release and operative positions and each of the jaw pieces is provided with a relatively involutedly shaped portion such that when a shaped work piece having a similar involutedly shaped profile is placed between the opposing involutedly shaped jaw portions the work piece is securely held in such a manner that it may be machined without substantially damaging or distorting the work piece. Additionally, there is provided a jig arrangement for holding the jaw pieces to form a vice arrangement and a method of using the jaw pieces, vice arrangement and jig arrangement is described.
