What happen if not doing bow rehair

The other day I found my bow's hair couldn't be tighten.

I guessed that it was because I didn't  do bow rehair for long time.

Furthermore the part of bow's frog seem to break , so my bow couldn't adjust how tighten my bow's hair is.

We can see a frog on the frog -1 

We can see a crack on the frog -2

In the case it is expected that my bow will completely break during our performance. As I want to be avoid such a situation, I thought I took measure to my bow.


Going to the repair shop I was said that it is too hard to repair it. And they explained the reason and the structure of the bow.


According to their explanation, my bow's hair has so completely stretched and movable space to adjust how tighten my bow's is has used fully that I can not tighten more.

Moreover , even though in such a case if I turn a screw by force, the screw may break.



They say it takes me as same money as I buy a new one. So I hesitate over whether to buy the new one or to borrow from my acquaintance for time being to get over performance.


Fortunately I could find acquaintance to lend me bow, I decided to use it.


But it is true my bow is so old that I buy a new one after tomorrow's performance.
