Ringeck's quoted lesson describes Duplieren as an aggressive follow-up after a Zornhau exchange, with interpretations centred on a long-edge slice across the face. Its name is explained as doubling or folding over, which helps connect the term to the movement. At excessive range, the action works only if the opponent is distracted, since the crossed swords no longer control the counter. At close range, a strong tight motion and crossed-sword defence can make a counter-thrust difficult while allowing the slice to land with force.
