This cable attaches between the head and shaft of a Fly or Superfly axe and enables them to take a clipper leash that attaches via a mini-karabiner, such as DMM's Rebel Leash.
NB It does not fit the latest generation of Flys - the axes need to have two holes through the shaft near the head to take the cable kit.
Price is per cable (ie will do one axe), however, there is no reason why you can't just do one axe as most people place gear with one hand - usually the same one.
It does not include the clipper leash itself.
