The Double Fisherman's knot
Despite the uptake of knots like the overhand
for tying two ropes together, the double fisherman's remains the safest way to do this in the
climbing environment. It is also the only knot to use to join ropes of different diameters as it
is resistant to the unequal stretching in the ropes that this can induce.
|Ease of Tying||Not simple - it is easy to get the orientation of the loops wrong.|
|Also known as||Grapevine Knot|
|Usage||Tying two ropes together end to end. Often used to tie the cord on larger chocks in this fashion.|
Can be used to join two ropes of different diameters.
