Hi mate With this one I think it's just bad luck rather than the willow. The toe of a bat is naturally a weak spot and this looks like you caught one of the very corner.Repair wide open her up a bit so you can get glue right the way down (a syringe or straw will be handy here). Then clamp overnight. If you wrap tightly with tape now, with any luck it shouldn't get any worse.Final tip, but another bat or 2, then you don't need to worry about things like this happening to your only one
