A wristguard is a piece of armor designed to protect the wrist and forearm from impact; it might also be called a “vambrace”. It’s a period artifact, but no period examples of its use as an heraldic charge are known. The illustration is based on a Spanish vambrace dated c.1550 [Stone 653]. The wristguard is palewise by Society default.

In period armory, there is also the “coudière” or “elbow guard”, to protect the elbow; it was the badge of Ratcliffe (Radeclyff), Lord Fitzwalter, 1513 [Walden 212; HB 136].  There was also the full arm armor, from shoulder to fingertips, including the gauntlet; this was the badge of Bourgh (Bourght, Borough) de Gaynsbourght, c.1510 [Walden 251; HB 79].  This is correctly termed a “garbralle” or “garde-bras”, though the term was also used in period for the coudière; technically, any protection for the arm could be considered a garde-bras, that being the literal meaning of the term.

The Order of the Silver Guard, of Drachenwald, bears:  A silver wristguard bearing a dragon passant coward, wings addorsed, maintaining in dexter forepaw a sword erect.
