What does piton mean?
A piton is a metal spike driven into rock or ice to serve as an anchor for a climbing rope. Climbers may hammer a piton into a crack, place it in a drilled hole, or clip a sling or rope through its eye. The word belongs mainly to mountaineering and climbing terminology and suggests both the practical equipment used on a route and the traditional technique of protecting a climb with hardware fixed directly into the mountain. Although modern bolts and removable anchors are widely preferred on many rock routes, pitons are still regularly used in ice climbing and traditional routes. Outside those contexts, the word is uncommon and should not be used as a general synonym for any pointed metal object.

- A metal spike or peg driven into rock or ice to secure a climbing rope or provide an anchor point.

Where does piton come from?
The English word was borrowed from French piton, a term associated with Old French pignon, meaning a peak, point, or summit. The English mountaineering sense developed during the nineteenth century as climbing techniques and specialized metal equipment became increasingly standardized.
How piton is actually used
Piton is primarily technical mountaineering vocabulary. In modern climbing, bolts and removable anchors are often preferred because they cause less damage to the rock, but pitons remain common in ice climbing and traditional routes.
