Absetzen with Ochs
This video shows how to do Absezten versus Zornhau with Ochs.
Absetzen (offsetting) are parries in opposition where the guards Ochs and Pflug are used to displace and thrust at the same time. Like all single-time counters, Absetzen are very effective interceptive strikes which are nearly unstoppable - if and when done correctly. However they require the fencer to act early and precisely in order to succeed.
