The double fisherman's knot is used to tie two ends of equal diameter cord together to make a prusik or cordelette. It can also be used as an alternative to the overhand to join ropes for abseiling.

Step 1
Loop one end of the cord around the other end twice, then push the end through these loops.

Triple Fisherman's Knot
Some cord or rope may be too slick or stiff for the double fisherman's to work. In this case, try adding an extra loop to each side of the cord to make a triple fisherman's knot.
