Our Shield Boss Power Surge Iron With Rivets is premiere quality iron. The Roman Empire is the earliest to date to use the shield boss and from there its popularity grew over time. The earliest versions of the shield boss were said to have a pointed top but often broke during battle. The Romans then rounded the tip of the shield boss enough to cause damage but still maintain its stature in the roughest of battles. The shield boss is also an ideal attachment for your shield to help decorate, defend, and stabilize the center spine of the shield. War is always going to be around but the best equipped soldiers usually come out of the battle alive. Specifications Material: Iron Depth: 2.5 in. Width: 6.5 in. Screw Holes (4): 0.25 in.
