There’s no register of mountaineering icons that we are aware of, but if there were, then there’s no doubt that the Chouinard ‘Zero’ Ice axe would be on it. Created by American Yvon Chouinard in 1976, the ‘Zero’ quickly became the most sought after ice axe of the era and that’s still the case some forty years later when ‘Zeros’ sell for ten times their original price – albeit more as collectors’ items than for practical use.

Surprisingly, for something so good, its active life was short. The 1970s and 80s was a period of great change in the mountaineering world, with technology rapidly overtaking tradition. Wooden shafted ice axes had been the norm since the sport of mountaineering began, but the demand of ever harder climbs required stronger ice-axes. The early ‘Zeros’ were wooden shafted, some with laminated bamboo – it’s these versions that have gone on to become the collectors’ items.

The version we have here in the collection is a somewhat later, glass fibre shafted version, an attempt to move with the times which didn’t work too well. Drooped pick ice tools began to appear on the market in the 1980s and were found to be much better for climbing steep ice. The Zero’s brief period of iconic life was all but over.

The ‘Interalp CAMP’ logo on this, and various other items of gear, often confuses folk. It basically refers to a big factory that produces things ‘en masse’ and on licence to the original manufacturer to reduce costs. Chouinard, for instance, originally produced his ice axes at the Great Pacific Iron Works in California, but later transferred production to CAMP in Italy because it was cheaper.
