How to Use This Shield Boss
This umbo is ideal for creating your own functional shield for LARP, light historical combat, reenactment, theatre, or as part of a costume. It not only provides protection for the center of your shield and your hand but also ensures proper balance and historical accuracy. It's an excellent choice for reconstructions from the Viking Age to the High Middle Ages.
IMPORTANT NOTICE: Although the boss is made of steel, it is mild steel, and the product is not designed or certified for full-contact combat such as HMB, Buhurt, Battle of the Nations, or similar sport disciplines. It is intended for light combat, parades, and display purposes.
A Fun Fact from History
Did you know that Roman legionaries used the umbo on their shield (scutum) for more than just passive defense? It was also an effective weapon. In close-quarters combat, legionaries would punch with the boss (in Latin, umbone pulsatim) to unbalance an opponent or injure their face, creating an opening for an immediate attack with their gladius sword. The boss was thus a key element in both defense and offense.
How to Care for Your Boss
To keep your shield boss shiny and prevent rust, follow these simple steps:
- After each use, especially in damp conditions, wipe the boss thoroughly dry.
- Regularly apply a thin coat of mineral oil, conservation wax, or even a standard product like WD-40.
- Store it in a dry place to avoid contact with moisture.
