View source for Einhorn Device 4

''Note when you have flown out to both sides and come into the Unicorn above you, if your opponent then strikes from his right to the left of your head, then step with your right foot toward his left well away from his strike, and then drop onto the strong of his sword (such that your hands stay crosswise) with the short edge above. This requires an offstep every time which shall be completed at the same time as his oncoming strike, and just as the swords glide together in this way, just then let the short edge snap off again up from his sword, and hit him with it over his hands to his head, after this strike with the long edge and an outstep. From this Unicorn you can also fence and attack rightly and well with the understrike and the thwart, as many good plays shall also go onward similarly when you consider it afterward.''
