The intended use was for a victim to kneel on their knees, back straight up, and the executioner to stand behind them and basically take a baseball swing at their neck. The tip is not sharpened, but often left blunt, rounded, or squared. It features a very heavy, short blade, made to be swung with 2 hands even though it's the length of a 1-handed sword. Historically, it was used mainly in Germany exclusively for the execution of criminals, not for combat.
So I was toying with ideas, and came across the Executioner's Sword.
