There is one little thing that I think should be mentioned. If doing Irimi Ikkyo you initially stay on the line of attack and deflect the attack with a slight movement. Practising this gives an excellent insight into 'FIRST CONTACT' in combat and redirection into the point of non balance. Big or small, that is how you deal with everyone in an ideal
world, unless you are extremely skilled though (or your attacker is easy pickings), in real
world ATEMI first, unbalance later!
