Description & Commentary:

In the 1970s, pioneering US climber Royal Robbins imported carabiners from the German company Salewa. Unlike other carabiners in the day, Salewa constructed these lightweight carabiners constructed from hollow tubing and individually tested each one (to 1000kg).

The nose and tail of the carabiner were formed by smashing the tubing flat before forming the notch and hole for the hinge pin. Although challenging to see in these photos, the gate is stamped "tested" along with the other more clearly seen markings along the spine.

Other than the hollow tubing, this carabiner is hardly remarkable - a testament to the usefulness of an oval carabiner since we still see similar designs today. This particular example lived a hard life on the rock and has the scars to prove it.

Salewa applied for a patent in the US in 1977, approved in 1978. I do not know if they were being sold prior to the patent application date. If anyone has a photo of these being advertised (perhaps in a catalog from Royal Robbin's Mountain Paraphernalia import business), please contact me.
