During battle when a weapon breaks, another weapon/tool is auto-equipped. I don't like this, often an axe or even a knife is equipped automatically, which i don't notice - thus automatically reducing my damage dealing - and then using up a tool which I would never use in combat anyway. Especially since I have swords and short sword in my inventory.
Not sure what you might do about it ..
* visual cue that my weapon is damaged, while removing auto-equip.
* smarter auto-equip
