What is notable so far is the absence of any Shotley Bridge hollow ground blades. Nonsense to one side about the story of mercury filled blades naturally a joke in the trade at the time... but I have also heard of the term applied to the cutting edge as hollow grinding... To some extent that may be partly true but the Hollow Ground
blade or Colichemarde
form is much more interesting than simply that. Colichemarde were broader toward the throat with about 12 inches of quite thick broad blade sweeping to a narrower long blade of three edges; Triangular in cross section leading to a sharp point.
If there are none from Shotley Bridge could it mean that they either produced so few by hand (Solingen it is said churned these out with a grinding machine) or that Shotley, without the machine, gave up trying to compete? ...but the net effect is I am unable to source a single Hollow Blade of this type from there..
According to Wiki Quote"The Colichemarde blade configuration is widely thought to have been an invention of Graf von Königsmark, due 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. "Unquote.
