usually I am very optimistic bout fixing things,, that looks bad,,, I dry fired a sinew bow with similar results,,, I sinew wrapped the whole break,,, and it worked,, did not fall apart,, but was never the same ,, tiller or performance,,, you could try that as you have nothing to loose at this point,, it is to your advantage that the break did not go to the back,,the sinew wrap should be thick,, we are not going for a beauty contest at this point,, just seeing if you can get it to hold together,, I know alot are going to post that it is toast,, and that may be true,, but it sure wont hurt to see what happens if you wrap it,, assuming you are wearing your safety gear to test it
