Summary:unique reverse-keylock gate with hidden spring
Description & Commentary:

The gate itself is essentially an undersized solid rod, with a small loop formed on the hinge end positioned around the hinge/pivot pin. The nose end is expanded and slots into a gap in the nose of the carabiner, above a constriction.

Sometimes called a wiregate, I classify this as a solid gate carabiner with a reverse-keylock nose. In a traditional wiregate, the gate itself provides the gate-closing spring pressure. The Petzl Ang has a spring in the body of the carabiner which pushes against the hinge end of the gate.

It sports a plastic piece on the gate to provide a flat bearing surface, which helps resist the carabiner from twisting out of the hand in use.

Interestingly, this carabiner has a minimum major axis strength of 20 kN, uncommonly low for a modern carabiner.

While not particularly useful for my tree climbing needs, I am impressed with how light and compact the Ang S feels in my hand. The finish and workmanship is everything you'd expect from Petzl. Also available in a larger configuration as the Ang L.
