Wrap the cord in a thin plastic film. Pass it into the eyelet of the kurikata. Remove the plastic film wrap.
Pull the cord through the hold until half of it goes through. Double over the cord across the kurikata and make a simple loop with both the free ends of the cord.
Pull both ends through this loop to make a knot. This makes the warrior's sageo tie. However, a decorative sageo tie can proceed with more knots.
Wrap the cord in a thin plastic film. Pass it into the eyelet of the kurikata. Remove the plastic film wrap. Pull the cord through the hold, until half of it is through.
Cross the arms of the cord at the kurikata knob to form an X-shape.
Pull both arms of the cord under and behind the scabbard. Make a small hole on each arm of the crisscross. Insert a short loop of each free of the cord into the corresponding hole on its side of the knob. This will give two knots which look like a weave pattern.
Repeat the weave pattern, making the same two knots on each side of the knob -- following the directions in Step 3.
Pass what is left of each free end of the cord through the row of knots. Fold each end over and pass again in the other direction. Pull the ends for a tighter fit.
