Also much more even cutting, as in ending up with hammers more closely  
equal in width. The knife goes through lacquer reinforced felt more  
positively than the less dense felt, where it could (and did) tend to  
wander a bit from side to side. Or maybe it would be more accurate to  
say that the felt wanders(ed) under the knife. That was the  
explanation I was given for the change, and it makes a lot of sense,  
based on my experience in cutting various felts. WIth a denser felt,  
this is less of an issue.
