Very few items of mountaineering equipment have stood the test of time as well as these Chouinard Hexentrics which were granted a US patent in 1976 and are still much used by rock climbers in 2012 and will be, we suspect, for some time to come.
Hexes, as they are affectionately known, were invented by American climbers Yvon Chouinard and Tom Frost, who took a standard hexagonal shape and 'offset' it a little to make it wedge better in rocky cracks - like most good things in life - very simple and very effective. Chouinard sold out to a company called Black Diamond in 1989 and they continued with the successful formula into the new millenium and look like carrying on for a bit yet.
