The teacher I had when I first started playing, made a reed from steel, I imagine it was I bit like a Razor Blade,. Ouch! He only tried it once.There was a story that Earl Bostic had part of a razor blade inside his mouthpiece. Either that was a myth or it was an early example of the metal spoiler that can be inserted in some Runyon mouthpieces to give an aggressive sound.
