The term 'kind of knot' can refer to four different knots: the GRANNY knot (6 letters), the GORDIAN knot (7 letters), the HITCH knot (5 letters), and the BOWLINE knot (7 letters). The GRANNY knot is a simple knot used for tying two pieces of rope together. The GORDIAN knot is an intricate knot that was famously cut by Alexander the Great. The HITCH knot is a type of knot used to attach a rope to an object. Finally, the BOWLINE knot is a knot used to form a loop at the end of a rope.
