It is holding together fine!
I think if it would have broken any further forward it would have been a problem. However, in this case the pressure of the scales against the tang isn't really near the break. So, the glue ought to be able to hold it in place since the break doesn't have any stress on it.
I can see dying these black after some polishing to hide the crack, but this is good enough for now.
