Edward Whymper,
Scrambles Amongst the Alps in the Years 1860-69
“ There is no better weapon for cutting steps in ice than a common pick-axe, and the form of ice-axe which is now usually employed by the best guides is very like a miniature pick. My own axe is copied from Melchior Anderegg’s. It is of wrought iron, with point and edge steeled. Its weight, including spiked handle, is four pounds. For cutting steps in ice the pointed end of the head is almost exclusively employed: the adze-end is handy for polishing them up, but is principally used for cutting in hard snow. Apart from its value as a cutting weapon, it is invaluable as a grapnel. ”
