The “Sinsheimer Wetzstoispucker” stands in life size, gnarled, connected to the earth as a water-spitting fountain figure on Karlsplatz. As the symbolic figure of the "Wetzstoispucker", the artist did not choose a vigorous, upright Hercules, but a figure corresponding to the economic and social conditions, which is similar to a former farmer from Sinsheim.
According to old oral tradition, the people of Sinsheim are said to have stood up to their ankles in the water and mowed reeds on the moat, on the Untertorwiese or on today's Karlsplatz, which was a marshy meadow in front of the city wall before 1820. In this business the scythes often became blunt and had to be sharpened with a whetstone. Although the mowers were deep in the water, they would have spat on the whetstone instead of dipping it in water or in the water-filled "body" hanging from the waist strap. This is said to have been observed by some foreigners, and since then the people of Sinsheim have been nicknamed "Wetzstoispucker".
