Medieval Steel Shield Boss (Umbo) – Polished, 7.5 Inch

Medieval Steel Shield Boss (Umbo) – Polished, 7.5 Inch

Construction and Features

Forged from durable mild steel, this boss is built for use. The exterior features a polished finish, giving it a striking appearance on the battlefield and making it easier to clean. The interior is blackened to help prevent rust accumulation from condensation or humidity.

Unlike standard bosses with only four holes, this model features a wide flange with six pre-drilled mounting holes. This ensures a secure, rattle-free fit against the wood of your shield, even during rigorous reenactment use. A set of rivets is included, so you have everything you need to attach it immediately.

Historical Context

The shield boss was a vital component of personal defense for centuries. On center-grip shields, common among Vikings, Saxons, and Celts, the boss covered the hole cut into the center of the shield board. This allowed the warrior to hold the shield directly behind the boss, making the shield an extension of the arm. This setup turned the shield into an active weapon, used to deflect blades and deliver crushing punches with the steel dome.

Care Instructions

As this item is made from mild steel, it requires maintenance to prevent rust:

• Storage: Always store in a dry environment. Avoid damp basements or leaving it in wet gear bags.
• Cleaning: Wipe clean with a dry cloth after every handling or use.
• Oiling: Apply a light coat of oil (such as mineral oil, gun oil, or WD-40) regularly to create a protective barrier against oxidation.
