GRAPEVINE
OR DOUBLE
FISHERMAN'S
KNOT

This knot is particularly
suitable for fishermen
who use it on their lines
for more secure joints. It
is suitable only for thin
line and string, because
it is quite bulky. The
grapevine knot is used
by campers on tent guy
ropes or to join lengths
of string used for tying
up or hanging objects,
etc. It is also used by
climbers on small stuff.
