LARP Medieval Steel Shield Boss – Textured Battle-Worn Umbo for DIY Shields

Forge your own shield worthy of the battlefield with this LARP-ready Medieval Shield Boss (Umbo). Handcrafted from solid 14-gauge mild steel, this boss is designed to protect the fighter’s grip while adding an authentic medieval or Viking-age look to your shield build. The deeply domed center gives ample room for hand clearance in combat, while the textured, weathered finish makes your shield look like it has already seen countless campaigns. Pre-drilled with six mounting holes and supplied with rivets, it’s battle-ready for quick assembly—whether you’re finishing a Viking round shield, reinforcing a medieval buckler, or upgrading your current kit. Perfect for LARP warriors, and DIY armorers, this umbo provides both historical style and rugged practicality. Its hammered texture mirrors period blacksmithing and looks striking in both daylight and torchlight during events. Measurements (Approx.)
