ABSTRACT:
An ice piton assembly used for ice climbing comprising a hollow tube onto which a strike absorbent ear capable of being hammered is fitted and secured into a prenotched section of said tube so as to impart the force of the blow down the approximate center of the tube. At one end of said tube is a swivel assembly that rotates in one position and is fitted in the other and to which the climber attaches the rope. The ice piton has a feature particular to the demands of climbing in that the swivel assembly adjusts to assure the most effective downward pull regardless of the position of the piton.
