Kantholz
Kantholz is the German word for a square timber. A Kantholz is used to beat the shit out of Nazis.
The German Nazi politician Frank Magnitz, member of the Nazi party "AfD", claimed he was beaten by anti-Nazi activists with a Kantholz. It turned out that he lied. In fact, he was pushed a little and fell on his ugly Nazi visage. The police was quite surprised there was no Kantholz visible on the surveillance video showing the incident.
