Hand-Forged Steel Shield Boss 'Umbo' for Viking Shields, 2mm
Appearance and Construction
This shield boss, technically known as an umbo, features a classic domed profile, perfect for deflecting blows from swords, axes, and spears. It's forged from a single piece of steel for maximum durability. The boss is framed by a wide flange with six pre-drilled holes, allowing for a fast and secure attachment to your wooden shield board. The dark, matte antiqued finish not only looks incredible but also provides a layer of protection against corrosion.
Use and Assembly
Thanks to its solid 2mm mild steel construction, this boss is not just for show. It's crafted to withstand the rigors of historical fencing, reenactment battles, and dedicated training. You can use it to create a Viking round shield, a Norman kite shield, or any early medieval shield design.
Assembly is straightforward. Place the umbo in the center of your shield board and use the included rivets and washers to secure it firmly. For the most authentic and durable fit, we recommend carefully peening the rivets over the washers on the back of the shield.

A Glimpse into History
The shield boss was an essential component of shields from antiquity through the High Middle Ages. It allowed a warrior to grip the shield via a central handle, while the metal dome protected their hand from direct strikes. The raised shape helped redirect enemy blows, significantly extending the life of the wooden shield and, most importantly, protecting its wielder. This style of umbo is characteristic of those used by Norse, Saxon, and Norman warriors.
An Interesting Historical Fact
While primarily a defensive element, the boss could also be used offensively. A skilled warrior could use a direct, forceful thrust with the center of the shield (a "shield punch") to strike an opponent's face or body. This surprising and painful tactic could stun an enemy, creating a vital opening for a sword or axe attack.
Taking Care of Your Umbo
As this piece is crafted from carbon steel, it is susceptible to rust. To ensure it serves you for years to come, follow these simple care instructions:
- After each use, especially in damp conditions, wipe the boss down thoroughly with a dry cloth.
- For long-term storage, apply a thin coat of protective oil (such as WD-40, mineral oil, or wax).
- Always store your shield in a dry location. Prolonged exposure to humidity is steel's greatest enemy.
- Clean with a dry cloth only; do not use water or abrasive materials.
Note on Craftsmanship: Each piece is individually hand-forged. Please expect minor variations in texture, patina, and hammer marks. These are not defects but a testament to true, hands-on craftsmanship.
