For some reason, toward the end of the video, I begin to refer to the "Cross the Face Elbow Strike" as an "Elbow Chop" ~ It bothers me, but I hope everyone else can overlook that. lol

This information is posted for Nihon Goshin Aikido Study Groups. The book, Nihon Goshin Aikido: The Art and Science of Self Defense by Jeffry Dutton, and the videos by Shihan MacEwen, and your Nihon Goshin Aikido Sensei should be your primary resources for mastering this technique..
