Langes Messer training sword

The 'Langes Messer' (Long Knife) is a single-edged sword originally developed in 15th-century Germany as a personal defense weapon. In the modern era, this product is primarily manufactured by specialized HEMA (Historical European Martial Arts) equipment suppliers such as Landsknecht Emporium in Hungary, Regenyei Armoury in Hungary, or various smiths across Europe and Asia.

Because these training tools are often hand-forged or semi-customized for the martial arts community, they do not belong to a single global corporation but are instead produced by niche manufacturers specializing in historical accuracy and safety for competitive fencing. They are commonly used by practitioners studying historical manuals, such as those by Johannes Lecküchner, which are often displayed in the background of such training facilities.
