Usage notes

 * In modern discussions of historical armor, a distinction is often drawn between a close helmet, where the visor and (single) bevor swing forward to open the helmet so it can be put on, and an, in which the left and right cheek plates swing apart to the left and right (upwards or backwards) to permit the helmet to be put on. In the Late Middle Ages and Renaissance, when such helmets were in use, the terms were sometimes used interchangeably.
