Antique iron railroad spike featuring square shaft, tapered point, and flat head. Likely hand-forged or early industrial era piece. Shows heavy patina, oxidation, and surface wear consistent with age and outdoor use. No visible modern markings. Approx. length: ~6–7 inches (see ruler photo). Great for blacksmithing, repurposing (knife making, hooks, decor), or industrial display. Photos may show slight color variation due to lighting.
