This is a technique featured in phase one level two of Shu Ha Ri Do. This is what I call “simultaneous block and strike”. To do the technique correctly you must be sure to move your head in addition to the slip block. The slip block is like guiding your opponents punch over your shoulder and returning a strike at the same time. Repetition is key to mastering this and any other technique. You must repeat, repeat, repeat, and repeat again.
