Uh...,  Wim...,

Filing a tuning fork makes it smaller and therefore sharper.  I know that a 
fork can be filed at the base of the tines to make a fine adjustment in the 
flat direction, but 440Hz to 415Hz is NOT a vernier adjustment.

Maybe you've come up with a technique to file something longer???  ;-}
