The Columbia Police Grenade is a compact, cylindrical explosive device with an Art Deco-inspired design, featuring intricate geometric patterns engraved into its metallic surface. The grenade has a polished brass finish with subtle weathering to indicate use, and a prominent, red-striped safety lever that contrasts sharply against the metallic body. Its form is sleek and functional, with a slightly tapered top for easy throwing, embodying the steampunk aesthetic with visible rivets and a small, glowing fuse mechanism at the base.
