Usage
The Underwriter's Knot is used in electrical applications to reduce strain on the terminal leads of a wire. A hair dryer, for example, will use the Underwriter's knot to protect the wire connections inside. If the hair dryer is accidentally dropped or the cord is pulled, the knot, found just inside the housing, removes the strain from the wires where they attach to the electronics inside.

Structure
The Underwriter's Knot is unique in that it is typically tied in two-strand wire used for electrical purposes. The two wires are typically joined together by an insulated covering that is split down the center leaving two short working ends that are used to form the knot.
