As with all "bends," the figure 8 bend joins the ends of two ropes. After holding a heavy load, the figure 8 bend is easier to untie than most bends (e.g., a double fisherman's bend, ring bend, or water knot). Once you are familiar with tying figure 8 knots, it's easy to remember how to tie a figure 8 bend. Note that the figure 8 bend is a little bulkier than other bends and it takes a little longer to tie and dress.
vRigger costs less than a rope.
