Shape

Heater shields developed in the late 12th century. Although they evolved from kite shields, they were more manageable and used either mounted or on foot. As plate armor began to cover more and more of the body, the shield grew correspondingly smaller. Relatively lightweight compared to other similar shields, the heater shield was easy to move around during both mounted and on-foot combat.

Because they were relatively inexpensive and easy to make, they were used by almost every social class. 

Design

The “pale” is a vertical stripe that runs down the center of the shield. It represents great military or defensive strength and is derived from the word “pale,” meaning a sharpened stake driven into the ground. Palings formed defensive walls around settlements, camps, and forts.
