Let’s start at the beginning. When the first film arrived on screen there was nothing like the weapon seen here. It was primal and evoked images of talons and claws, but the construction was conceived as using things found in a boiler room or basement, hence the copper pipes and general “Scrap parts” look used in the opening scene of the film.
Specifications: 3/4 in. Type-M copper Pipe, .02 brass, Spring steel blades.
