The Petzl Trigrest is an adjustable hand rest for Quark, Nomic and Ergo ice axes.
The Trigrest can be adjusted without the need for tools on either the shaft on handle of the axe. It has two support positions: a brace for hand switching in the high position, and a brace for the index in the low position. The latter increases grip strength for leashless climbing and improves planting precision. The Trigrest may also be used in a fixed position, without the index support.
