Nope, they're radiused in the holes. It's just a standard 
agraffe cut off about half way through the hole, with the hole 
otherwise unmodified. In fact, if you could get them to line 
up, you could cut the tops off of the agraffes lower down, use 
them in the "capo" section, and have a virgin string contact 
surface to work with, replacing the modified agraffes with new.
