14-Gauge Copper-Plated Medieval Shield Boss Umbo with Rivets

Bring your medieval shield to life with this historically inspired copper-plated shield boss. Forged from tough 14-gauge mild steel and finished in a distinctive copper plating, this umbo adds not only structural reinforcement but striking aesthetic appeal to any round shield build.

The traditional domed design offers crucial knuckle protection in battle while allowing deflection of incoming blows—just as seen in Viking and Norman combat. This boss includes 8 pre-drilled holes and rivets for mounting, making it perfect for attaching to wooden shields whether you’re crafting for LARP, historical training.

The unique copper finish sets your shield apart from the usual plain steel versions, evoking status and detail in any warrior’s kit. This is not a flimsy costume piece—its 14-gauge construction ensures real functionality and resilience on the field.
