In page Ice axe:
"In 1978, the Safety Commission of the Union Internationale des Associations d'Alpinisme (UIAA) established formal standards for ice axe safety and performance. This led to the replacement of the traditional wooden shaft by metal alloy shafts. Ergonomically curved handles became widespread in 1986.[1] Use of modern aluminum alloys have led to a dramatic reduction in the weight of some ice axes. One model now on the market, the C.A.M.P. Corsa, weighs only 205 g (7.2 oz) with a 50-centimetre-long (20 in) shaft. One expert rated this lightweight ice axe as "ideal for low angle glacier travel" but said he "craved the solid and secure heft of a true steel mountain ax" in more demanding steep alpine conditions.[7]
