vambrace

Vambraces (sometimes known as lower cannons in the Middle Ages) are "tubular" or "gutter" defenses for the forearm, developed first in the ancient world mainly by the Romans, but only formally named during the early 14th century, as part of a suit of plate armour. They were made of either leather, sometimes reinforced with longitudinal strips of hardened hide or metal (a crafting method named "splinted armour"), or from a single piece of worked steel and worn with other pieces of armour. Vambraces are generally called forearm guards, with or without separate couters.

"tubular" or "gutter" defenses for the forearm, developing first during the 14th century. During the whole transitional period , many materials were experimented with leather, sometimes reinforced with longitudinal strips; iron; with or without separate couters. Generally laced directly to the underlying mail, by 1335 in England the mail was reduced and the vambrace was attached to the couter via lames and rivets (see arm harness). The use of iron was essentially introduced at that time. Splinted vambraces were popular in Germany and in Italy during the whole of the 14th century, featuring heavy, possibly tooled leather and reinforced with longitudinal strips of metal.
