ABSTRACT:
Apparatus and method for trimming a reed used in conjunction with a musical instrument includes a support structure and at least one cutting instrument that can be manually coupled to and removed from the support structure. When the cutting instrument is positioned in the support structure, the reed is inserted between a die portion and a punching portion of the cutting instrument. A force applied to a lever mechanism coupled to the support member forces the punching member in to the plane of the die portion thereby trimming the edge of the reed. In addition to the convenient interchangeability of the cutting instruments permitting a plurality of reed sizes to be trimmed, the support structure can be fabricated from a single sheet of material. The number of parts needed for the apparatus is further reduced by having the lever mechanism comprised of two identical parts.
