The Grivel Single Spring Leash Evo is a lightweight and minimalist elastic leash for an ice axe and has been designed so that you do not to lose the axe during use but that it is easy to swap hands when you need to.
Rather than clipping on to the axe with a small karabiner, the axe is attached by inserting a toggle protected by a rubber pad into the hole in the head or ferule of the axe. Attachment to your harness or rucksack is via a 'lark's foot' in the loop (ie thread the whole leash through the loop). A swivel at the harness end avoids twisting and makes it smoother to use.
Materials: polyester, rubber, aluminium.
