The Fisherman's knot is a specialized bend. It consists of two overhand knots wrapped around each other.

It requires little dexterity, so it can be tied in stubborn materials with cold, wet hands. When tightened, it becomes very small and won't jam a mechanism such as a fishing rod. The free ends can be cropped very close to the knot. These qualities make it very useful for fishing line. However, bending a monofilament line into the tight curves of the overhand knots can generate enough heat to seriously weaken the line. Wetting the line before tightening the knot helps to dissipate the heat.

To tie the fisherman's knot, lay the two ends to be tied alongside each other and facing opposite ways. Tie an overhand knot on the first rope and pass the second rope through the loop formed. Tighten the overhand knot, to prevent the line inside it from flopping around. Then tie another overhand knot on the second rope with the first rope passing through it.
