A FRICTION KNOT FOR ASCENDING A ROPE OR
ESCAPING A BELAY
When tied properly, the klemheist knot (or Machard knot)
grips the rope when weighted but releases and slides along
the rope when the load is off. It releases and slides with
more ease than the prusik knot (see page 84) but grips with
less tenacity than the prusik. It works well for tying off a
climber’s rope to allow escape from the belay.
