Caution:
The blade of these swords are extremely sharp and may cause
serious injury. Make sure that the blade edge is never in a
position where it could injure yourself or others. If you need
to handle the blade, be extremely careful and wear protective
gloves.
Disassemble Procedures:
1. Use the mekugi-nuki (brass hammer) to remove the mekugi (peg)
from the handle. Since the peg is tapered, make sure you examine
it carefully to determine which direction to push the peg out.
(Note: You might need to use a rubber mallet to hammer out the
mekugi.)

2. Once you removed both bamboo pegs, grasp the handle with
the left hand and hold the sword in an upright position. Make
sure to keep the cutting edge away from the body. Then use your
right hand to hit your left wrist lightly to loosen the hilt.
Be careful not to hit the left wrist too hard with the right
hand as there is a danger that blades with short tangs might
bounce out of the hilt entirely.

Note: You might need to use a rubber mallet and tap lightly
on the tsuba if the handle is seized to the tang. Be sure to
wrap the tsuba with a cloth towel to protect it.

Assemble Procedures:
1. With the bare blade, slide the habaki (blade collar) onto
tang until it fits tightly against the mune-machi and ha-machi
notches.

2. Next, slide the seppa (washer), then tsuba (guard), then
the second seppa (washer), and finally the tsuka (handle) onto
the tang.

3. Grasp the handle with the left hand and hold the sword in
an upright position. Make sure to keep the cutting edge away
from the body. Tap the end of the handle upward with your right
palm until the pieces are firmly tightened together. (You might
need to use a rubber mallet to ensure a tight fit.)

4. Insert the 2 mekugi (pegs) to secure the tsuka to the blade.
