The 'Banyak Angrem' is an artistic dapur of a tombak spear. The shape of this type of tombak represents a goose incubating her egg. The asymmetric shape of the blade of this tombak is unique in the sense that most tombaks usually have a symmetric blade. Also, due to its unusual shape, the Banyak Angrem tombak is rather unpractical if used as a weapon for combat. It thus becomes clear that this type of tombak serves the purpose of a pusaka (heirloom), and as such it stresses more importance on esoteric powers.
