weird gear- or how to die 1-Dec-2009 At 12:26:07 PM mikl law

I had a near death experience in the 70's using these Hiebler clamps, apparently very good on iced ropes but they flick off all the time. Prussicing and jumaring before harnesses existed was not a great idea. You’d generally have one thin cord sling under your shoulders and a foot loop. And then find yourself hanging upside down from a foot loop. Of course I never used them on anything grander than a pine tree behind the boarding school I was incarcerated in.

You'd put them on with the lever facing up, under weight they would pinch the rope and rotate downwards (losing about 100mm of movement in the process each time). They gripped icy rope well as the rope was pinched and twisted too.

I found these on a crazy collector’s page, it's got every bit of manky gear I've ever seen
