casting of sword blades in the 19th century

[David R]

This is a conversation that has gone round and round over many years, even on this site. It is possible that the waters have been muddied by written references to "cast blades" which in fact meant "cast from service" and sold on, which is what happened to a lot of the 1796 sabres.
The billet may well have been "fluid cast steel" but it went through a forging and rolling process, which doubled it's length, halved it's thickness,and gave it a better grain, and more resilience. Even so blister steel aka shear steel was still being used for some blades right into the early 20th century.
Some bayonets were made by "drop forging" but still not cast. Below are pictures from a sword factory of automatic hammers and grind stones used in the forging of blades in the late 19th century.
I think if you want to back up the casting of blades theory we now need to see some evidence, video, photo or documentary.
