A reed clipper also known as a reed trimmer is a small tool used by clarinet or saxophone players to adjust the single reed music reed s used on those instruments. The clipper is used to trim off a portion from the tip of the reed. This can make a soft reed harder, or remove imperfections on the tip. A typical design involves fastening the reed onto the tripper by using a flexible strip of steel, and adjusting the height of the reed by using a knurled knob. Once the reed is positioned at the desired height, a small lever is pulled, which clips off a sliver of material from the tip. Another design, pioneered by the Vandoren company in the 1980s, involves the reed laying on a stationary table, positioned above a sharp blade. In this design, the cutting is accomplished by lowering a hinged lid which slides the reed tip against the blade.
