Only way you'll ever visibly reduce his health bar outside of grace is with the Maker's Finger, but when you go back it'll still reset anyway. When the grace period comes he'll have a sliver of health that you will be able to reduce to nothing, though it may take  a few tries. Some graces are tougher than others, but you have more than enough strength.
