The Shirasaya is a traditional Japanese sword mounting style that features a plain wooden scabbard (saya) and handle (tsuka) without ornate fittings or decorations. The Shirasaya is primarily used for storage and preservation of the sword blade, as it allows for the blade to be stored in a simple, minimalistic manner.

While it is technically possible to remove the blade from the Shirasaya and wield it in a fight, it is not ideal or recommended for several reasons. The Shirasaya lacks the necessary components for secure handling and proper grip, such as a guard (tsuba) and a wrapping (tsukamaki) on the handle. This makes it challenging to effectively control the sword and perform precise techniques.

Additionally, the Shirasaya is typically used to store swords that may be older, valuable, or in need of preservation. Engaging in combat with a sword from a Shirasaya can risk damage to the blade, as the wooden scabbard is not designed to withstand the forces and impact of combat.

If you are interested in learning swordsmanship or martial arts techniques, it is recommended to use a sword that is specifically designed and prepared for combat. Traditional Japanese swords, such as the katana or the bokken (a wooden practice sword designed to simulate a sword's weight and balance), are better suited for training and sparring purposes.

Proper training under the guidance of qualified instructors is essential for learning effective sword techniques, understanding the weapon's handling characteristics, and ensuring safety during practice.
