Sir Gawain's shield is known as the "Shield of Sir Gawain." It features a depiction of the pentangle, a five-pointed star symbolizing the five virtues of knighthood: generosity, fellowship, chastity, courtesy, and piety. The shield serves not only as a protective item but also as a representation of Gawain's character and ideals throughout his quest in "Sir Gawain and the Green Knight."

If we are talking Fire Emblem here, then my guess is Ragnell. But if your talking about King Arther's Sir Gawain, then you'll have to go on Google to find that out. But see, Ragnell was the name of King Arther's Sir Gawain's wife, i thank hats what I've heard, so that is why I say it is Ragnell. To add to this answer, I know nothing about Fire Emblem, but the previous answer is right in saying Ragnell is the name of Gawain's wife. However, his sword's name is Galatine (also Galatyn).
