Colichemarde According to Wikepedia.....The Colichemarde blade configuration is widely thought to have been an invention of Graf von Königsmark, owing to the similarity in pronunciation of their names. However, the first blades of this type date from before the Count's lifetime.
The colichemarde first appeared about 1680 and was popular during the next 40 years at the royal European courts. It was especially popular with the officers of the French and Indian War period. George Washington was presented with one during his inauguration.
The widespread misapprehension that the Colichemarde quickly ceased to be produced after 1720 dates to the opinion given by Sir Richard Burton in his "The Book of the Sword" dating to 1884. However, many securely dated colichemarde swords from as late as the 1770s can be found in collections.
This sword appeared at about the same time as the foil. However the foil was created for practicing fencing at court, while the Colichemarde was created for dueling. It made frequent appearances in the duels of New Orleans. A descendant of the Colichemarde is the épée, a modern fencing weapon.
