Like much of British mountaineering terminology we’ve borrowed the word Piton from the continent; in this case it is French and means ‘little peg’ but to the mountaineering world in general it’s a metal spike which can be driven into a crack in the rock. They come in all shapes and sizes and have been around for a long, long time; the earliest one being basically a metal spike driven into the rock for various industrial purposes. Local blacksmiths would have made the first mountaineering versions in the late 1800s, giving them fabulous names such as picture hook pitons and Mitzi Langer haken, though because karabiners were yet to be invented the climbing rope was simply hooked over them, or threaded through an attached rope loop or, later, a metal ring.

A blacksmith called Hans Fiechtl from the Tyrol area of Austria ( he might have also been a mountain guide) was one of the first to produce a piton with an integral eye around 1930, and this fits nicely with the arrival of karabiners which were being developed around the same time.

Dating from the 1960s these Cassin Horizontals are very similar to the Lost Arrow pitons made by an American, Yvonne Chouinard. These ones appear as No 12 in the 1963 George Fisher catalogue above. (2/9 = 14p).
