What is the primary use of duckbill pliers?

Duckbill pliers are primarily designed for twisting safety wire, which is essential in aviation maintenance to secure components and prevent them from loosening due to vibrations. The unique design of the duckbill pliers features long, narrow jaws that allow for precise manipulation of the wire, making it easier to create tight twists without damaging the wire itself or the components it is securing. This tool is favored in the aviation industry because it facilitates a secure connection that enhances safety and reliability in various structural applications. While duckbill pliers can also perform other tasks, their most effective and common use is indeed for twisting safety wire.
