A shirasaya, which means "concealing scabbard" (loosely translated), is a mostly-featureless Japanese sword meant for safe holding japanese blades when not in formal fittings. This style of mounting the blade was traditionally utilised for safe keeping or transporting a blade of importance.

Shirasaya became synonmous with the swords concealed as walking sticks when warriors had to hide them from the government.

Shirasaya style blades would likely never make their way onto a battle-field. However some examples of 'Shirasaya' type blades can be found in cloaked swords ( Ex. Hidden in canes, musical instruments, etc. )
