In reply to martinturner:
I have an idea there was a similar thread a couple of years ago but can't find it.
Oldest gear still in use would be a Snowdon Mouldings 'curver' ice axe which is still my 'walking axe' and a pair of Salewa bendy crampons which I still use with leather walking & telemark boots from time to time. Both bought in 1976 for my first trip to the Alps. More modern, but still used regularly, are a pair of Leki telescopic ski sticks (late 1980s). My collection of skis starts at about the same date although the older models haven't been used in a while.
Slightly older (by a year ?) but very rarely used are some Chouinard hexes although the rope has been changed a few times over the years.
Older still, maybe from 1972 or 3 is a Karrimor Pinnacle rucksac which I can't bring myself to throw - the remains are used as a stuff sack in the cellar. For several years it was my school, then college bag as well as in regular use for climbing & walking.
Although the oldest of all would be an Aschenbrener wooden handled ice axe which I inherited but have never used except as decoration. I've no idea how old it is & I'm (at least) the 3rd owner
