Ta-Metru workers often spend their time at forges just like this one, making tools, Vahki parts, and other items crucial to the running of the city. Vakama uses his forge and tools to make Kanohi masks. This is a very complicated process that involves carving a mask from a Kanoka disk or else melting down a disk and pouring the molten protodermis into a mold. Although Vakama has been a mask-maker for a while now, he has not made very many Great Masks.
