A bronze mattock is a mattock given to the player by Acting Guildmaster Reiniger during the Archaeology tutorial.
Even though it has the same combat stats as a regular bronze mattock, it cannot be wielded nor can it be banked. It can be added to the tool belt during the tutorial, although a regular bronze mattock will also suffice. Despite the destroy text, if you kept it in inventory by adding a regular bronze mattock to the tool belt, you cannot reclaim it after the tutorial if it is destroyed.
