Age Shuto Uke

Note: age shuto uke finishes almost the same as age uke, except that the block is with the shuto and not the fist/forearm
It starts with the blocking hand palm up in front of the sternum (left pic below). The palm turns to point up and the arm in a vertical manner (right pic below). When the fist reaches the final height, the elbow snaps out to complete the block.
