About Military Hair Brushes:
A military hair brush is a style of brush without a handle. It is a circular piece of wood inset with boar or nylon bristles. Its design is much like that of a horse's currycomb. It is meant for use with short hair and is thus often thought of as a man's hairbrush. Military hair brushes date back to the 1700s.
