Nice pics 'Vinta, 
 
Okay , I've wondered about this long enough . 
I have a couple of nice balisong from Batangas shops . 
I've found that you have to kind of tune them to get optimum performance as they, being hand made, are all a little different . 
 
What I want to know is ; what is the purpose of the beveled holes in the blade and the shallow notches on the false edge ? 
I got the bottle opener cut out figured ; that's easy enough ; but the other features have always puzzled me . 
 
What's up with them ?
