text: Ascenders are usually used in pairs, and offer similar functionality to friction knots, but are faster, safer and easier to use, albeit still with consequences in weight and in security (as ascenders can, even with a locking carabiner, come off the rope, and fail by shredding the rope at high loads, rather than slipping and fusing as with friction knots).
