Unsheathing the Blade (Nukidashi, 抜き出し)
Properly unsheathing a sword is the first step in any maintenance or appreciation session. Mishandling the blade can cause unnecessary wear to the edge (ha), scratches to the polish (hadome), and even accidents.
Steps for Safe Unsheathing:
- Prepare a Clean Work Area:
- Lay down a soft cloth or mat (tatami or microfiber surface) to rest the sword if necessary.
- Ensure good lighting to avoid handling errors.
- Hold the Sword Correctly:
- Stand or sit in a stable position.
- Hold the saya (scabbard) near its mouth (koiguchi) with your left hand.
- Hold the tsuka (hilt) with your right hand, keeping your fingers away from the cutting edge (ha).
- Draw the Blade Slowly and Straight:
- Pull the tsuka straight back while keeping the mune (spine) of the blade in contact with the inner wall of the saya.
- Avoid allowing the ha (edge) to scrape the inside of the saya, as this can cause dulling and residue buildup.
- Do not rush—drawing too quickly can cause loss of control or unnecessary wear on the scabbard’s interior.
- Maintain a Controlled Grip:
- Once the blade is fully drawn, hold it horizontally with the edge facing upward to prevent accidental cuts or dropping the sword.
- Avoid excessive handling of the blade’s surface, as fingerprints and moisture can lead to corrosion.
By following this method, the blade remains protected and the saya is preserved from internal damage.
