Press thumb up against the tsuba (hand guard) while holding the sheath of the sword.This should release the blade from the sheath.(no image needed)
Step 2: NUKI TSUKE (draw and cut)
From A sitting position (sitting on your feet toes pointed back and your knees touching the ground) you take your right hand and grasp the tsuka (handle)(your sitting position should stay the same except that you toes should now be under you so you can stand up if needed). Then you start to draw the sword from the saya and, start rotating both the saya and blade so that the ha (cutting edge) is pointing to your left after you have drawn half the blade. While you are doing this you should be on your left knee and your right foot should be on the ground next to it. Wile you are continuing to draw out the blade you should be rotating your upper torso slowly and when the blade is free from the saya you swing your arm that is holding the sword to your right. Have some self control when you do this, don't knock yourself over.
