This story mentions two types of shafted weapons that were used primarily in the Middle Ages. The German Hellebarde (English: Halberd)) and the Partisan, a subsequent form of the halberd. Early forms of the halberd were a combination of spear for military purposes and farm implement for work in the fields. The farmer in the story is carrying this type of combination tool, referred to first as a hay- or pitchfork and then as a partisan. The Swiss Guard, the oldest army in the world, still uses the Hellebarde to guard the Vatican.
Grimm's Saga 280:
The following story is told about the ancient Castle Lichtenberg in Hanau, perched on a tall cliff in Lower Elsass, an hour’s journey from Ingweiler:
When a storm or violent weather advances, one can see many small blue lights on the rooftops and spires of the castle, even on the tips of halberds. The lights have been seen for many years and according to some folk, this is how the old castle comes by its name.
Two farmers went out walking from the village Langenstein (close to Kirchhain in Upper Hesse) and walked toward Embsdorf with their pitchforks on their shoulders. On the way, one of the farmers saw a little light on the partisan of his comrade, who removed it from his shoulder and laughing, swept the eery glow away with his fingers so that it disappeared. After they had walked another hundred steps, the little light was once more at the prior spot and was brushed away again. But a few moments later it returned. The other farmer pushed it away with several harsh words, wiping it roughly once more and then it did not return. Eight days later at the same spot where the one farmer had brushed away the light for the third time, these two farmers met again. Normally they were old friends, but they became irritated with each other and their angry words led to blows. The one farmer stabbed the other to death.
