Crystal Cleaver T-155 by Tenyo (4481)

A ring (which may be borrowed) is placed into a crystal casket and the top is closed. The box is covered with an empty tube. A magical cleaver (a small sword) is inserted into the top of the tube, and then magically pushed down through the crystal casket and through the ring. When the tube is removed, the sword is through the ring inside the casket.
