Like Westbrook said, you don't abuse a bow, but don't baby them either...
I just got the first "nick" in my go-to...I was actually a little relieved (after the initial shock wore off), because now I don't have to worry about the first scratch...!
I saw a picture of Willie Nelson playing a guitar once, and that guitar was so worn out from strumming, that there was a long and wide HOLE in the front!!! At first, I couldn't believe that he would want to use a guitar in that condition...after thinking about it, I thought it was really GREAT! Like an old friend who's been with you through it all!
Honestly, a pristine bow in my opinion is not as beautiful as a used bow...
life leaves a mark, sooner or later...
It's a Memento Mori of sorts...embrace it!
