doesn't removing metal from the reed tip raise the pitch a tad?
Not only that, but doesnt rounding off the corners of the tip of a reed tend 
to make the reed a tad leakier than the reed's original squared off shape?  
  I'm sorry that i missed it, but what is the purpose or advantage of 
rounding off the corners of the end of the reeds?
