A tiny ampoule of steel and old, clotted blood, hung from a black iron chain, the Amulet of Dark Valor holds the drive of the furies.
A cave with weapons sunken into the walls, blades sticking out of the floor and ceiling, and so on. Possibly, any weapon used in it could be torn out of the hand and sink into the stone.
