A medieval shield weighed around 2.41 kg and measured approx. 59 cm in diameter.
Round, relatively lightweight steel shields like this one were primarily used between the 13th and 17th centuries. The shield's relatively light weight meant that warriors could quickly defend themselves with their arms more quickly and remain more mobile in general. Its 18 gauge steel guarantees a lot of protection, while the two leather handles on the back make the shield manageable. You can adjust them to use the shield with your left or right arm, as required.
This is a concave shield.
