Blades (of a chanter reed)
The blades of a pipe chanter reed (or a practice chanter reed) are the two pieces of cane, exactly symmetrical, that produce the vibration of the reed. They are placed around the staple of the reed, and bound together by the binding of the reed. Note: Don't use the term "blade" when talking about drone reeds. In that case, the vibrating object is called the "tongue."
