If you don’t mind Tom, just for clarification. A reed knife is a tool used by woodwind player (clarinet, bassoon, oboe,English horn,saxophone) to carefully custom shape the thickness of their instrument’s reed or double reed, to the correct thickness for the best sound. Players are very particular about this. The task requires an extremely sharp edge to thin out the reed, often just a hair thin difference from its original condition. I believe some players even fashion the whole reed from a blank but I will stand corrected on that. Did I get this right Tom?
