File Sharp Edges
Tue, 06/14/2011 - 07:13
Many harmonicas have sharp corners and edges left over from the manufacturing process. Take your finger and run it along all of the corners and edges of your harmonica... most likely you'll find a sharp metal corner or a place where the mold for a plastic comb left a high spot. You don't even need a metal file, a finger nail file will do the job just fine too.
