Art Ward demonstrating.
Begin in left hanmi with the jo held horizontally (left hand in middle of jo and right hand at the base). Swing the job slightly backwards and follow with choku tsuki but remain on the line-of-attack as you slide your feet forwards.
Now slide both feet to the right side of the line-of-attack (remain in left hanmi) as you slide your left hand to the front of the jo and "hide" the jo behind you. Finish with a sweep/strike at you opponents lower legs by turning your hips to the left, and stepping forwards with your right foot. Your right hand will push the jo in this strike.
