This is a bass bow where the break near the head is at a very obtuse angle. My first thought was to discard this bow because it's not worth grafting the crack together and it was too short of a break to simply glue and wrap it. Then after a month or so, I changed my mind and decided to save it. Here are the steps.
Drill a hole on the head side of the crack, then screw and glue it.
Cut the head off and taper the end a little.
Drill a hole that's correctly aligned and slightly larger than the stainless screw.
Glue the crack and the screw together and wrap and adjust a little to make sure it's straight and the camber is correct.
Smooth out stick.
Form some vulcanized fiber to the exact shape of the bow. Feather the edges similar to the way you fit a leather grip.
Glue the vulcanized fiber around the crack.
Make the fiber a little darker so it's closer to the bow's color.
Wrap the stick a little bit longer than the crack, but not as long as the fiber wrap

A violin bow with a long break that was missing some wood near the silver wrapping. I wrapped it a little longer than normal because I wanted the wrapping to stop at the silver. When I was gluing it together it was bent so I needed to clamp it straight while the glue was drying.

Here is a bow where the head was broken off and I repaired it about 15 years ago.
Just recently the stick cracked in a new place before the head and somehow some cloth fibers most likely from the case were jammed into the crack. I tried to get all of the fibers out of the crack and then glued it and wrapped the crack.
