In reply to jmerrick21:
I wish folk would stop confusing leashes and lanyards.
A leash is a wrist sling to support your hand when pulling on the axe. Modern climbing axes are so called " leashless".
A lanyard is to stop you dropping the axe. Confusingly they are often called leashes.
On older axes my favourite system, which Steve Reid introduced to me, is to make a lanyard of 5mm cord tied to the end of the leash connected to a point as close to my armpit as possible, it is then always the best length, whether using the head or handle of the axe. A screwgate on the shoulder strap of a rucksack or a bandolier being favourite. Mick Fowler famously used a similar system and once ended hanging from his rucksack too pumped to hold his axes.
Be careful if using the bandolier method as you can end up hanging from an armpit (or neck!) , a short link to the harness can sort this risk.
What I find a pain with leashless axes and a lanyard together is using the head of the axe when the spring lanyard is attached to the spike end from the belay loop.
