Mountaineering Equipment

Skyhook (Cliffhangers)
3-28. These are small hooks that cling to tiny rock protrusions, ledges, or flakes. Skyhooks require constant
tension and are used in a downward pull direction. The curved end will not straighten under body weight.
The base is designed to prevent rotation and aid stability.

PITON HAMMERS
3-29. A piton hammer has a flat metal head; a handle made of wood, metal, or fiberglass; and a blunt pick
on the opposite side of the hammer (Figure 3-14). A safety lanyard of nylon cord, webbing, or leather is
used to attach it to the climber The lanyard should be long enough to allow for full range of motion. Most
hammers are about 25.5 centimeters long and weigh 12 to 25 ounces. The primary use for a piton hammer
is to drive pitons, to be used as anchors, into the rock. The piton hammer can also be used to assist in
removing pitons, and in cleaning cracks and rock surfaces to prepare for inserting the piton. The type
selected should suit individual preference and the intended use.
