Abstract: A multifunctional hand tool is disclosed having multiple tool components for use to service and repair sprinkler and irrigation systems. The hand tool includes eight tool implements positioned on four reversible tool couplings. Each one of the four tool couplings are received by an end of one of two reversible servant couplings. The two servant couplings are each received by an end of a master coupling. The master coupling is received by a threaded insert. The insert is then received by a handle. The handle includes a retractable rotary head key for extracting a rotary sprinkler head, a releasable clamp, and a sprinkler nozzle adjustment mechanism for adjusting the spray pattern of a sprinkler nozzle.
