Very timely.  I had an occasion to drag out my 10-hole punch yesterday and 
modify a couple of diskettes for my N*.  The first time around I had a lot 
of tearing that resulted in the dreaded "hanging chads".  When I took a 
close look at the die plate I noticed an irregular raised burr around all 
the holes.  After taking some fine-grit sandpaper to the surface and 
leveling the holes it started working a lot better.

Maybe this will be helpful to other users.
