Scabbard
A scabbard is a sheath for a sword protecting it from both the elements and preventing the sword from damaging any object or individual with which it might otherwise interact. Scabbards would be constructed primarily of thin lathes of wood that would be wrapped in a covering, typically leather. linen could also be in addition to the leather or a more expensive fabric might be used as a covering. Apart from the covering, they might have decorations in the form of end mounts or metal fittings. They might also be lined with a material such as linen or sheepskin.
They were attached to a baldric or belt in order to place them in both a convient position and angle.
Some 14th century swords have additional guards that appear to have been attached to the crossguard of a sword that would help keep the weather out of the scabbard's mouth.
In Japan, scabbards were called saya and would be covered with a lacquer and would be used on many weapons such as spears and glaives. Japanese katana and smaller scabbards would be tucked in the belt, whilst larger swords had mounts attached to a belt of were carried in the hand.
