A plastic wrench for use on a boat with winch handle type caps. Winch handles damage the soft aluminium and give too much leverage causing over tightening and seizing. This wrench is short as caps are usually located in awkward spots and to prevent over tightening.
Also way cheaper than winch handles and stainless keys when they fall overboard.
