The image on the right shows a man in a Guard stance also called the Changer: stand with your right foot forward, hold your sword with the point near the ground and your arms outstretched so a cut with the false edge is threatened. (Change = Wechsel. See also Talhoffer tafel 2).
The man on the left stands in the Key stance: stand with your left foot forward, hold your sword by the grip with hands crossed in front of your chest and ready to strike, so the false edge lies against your left arm, and aim for your opponent's face.
