He can make a regular sword but not a katana, because of its slim yet incredibly sharp design. He must have struggled with that part
This is correct, but, if you just have the sword and don't know the need for dual steels (soft on the spine and hard on the edge), it must be REALLY difficult to recreate. Not to mention, the huge need for exhaustive labor by 6-8 craftsmen.We're really about to go on a multi-month arc on glazing the ever living crap out of glorious nippon 1000-fold forging technique using crappy iron sand. This whole technique was because the steel quality they had was shit and it was to make the material more homogeneous not because it magically made super steel
But imagine trying to reverse-engineer it with only the end result and no analytical tools beyond your own eyes and maybe some magnifying glasses.Katanas are no harder to forge than any other sword.
Folded steels are largely unnecessary if you have good steel like modern steels. Soft spine and hard edge can be done through differential heat treatment and/or lamination of two softer steels with a harder steel center. Theres nothing inherent about the process of making tamahagane that makes it better for any style of combat. Modern katana made with 1095 or T10 would be practically considered a mythical sword back in the dayThis is correct, but, if you just have the sword and don't know the need for dual steels (soft on the spine and hard on the edge, it must be REALLY difficult to recreate. Not to mention, the huge need for exhaustive labor by 6-8 craftsmen.
That doesn't make the blade anything special or powerful (Aesir says as much). But it's culturally significant and better suited to certain combat styles.
It's a one bladed two handed curved sword. There are hundreds of different styles of those kinds of Swords so wouldn't be that hard to figure out how to make a katana.But imagine trying to reverse-engineer it with only the end result and no analytical tools beyond your own eyes and maybe some magnifying glasses.
The exact process might be difficult to figure out (why would one consider using inferior raw materials if not by necessity), but a master blacksmith not being able to notice differential hardening makes no sense. Differential hardening/tempering was done at various points ancient europe, midde east, and asia, it's not exclusive to Japan.This is correct, but, if you just have the sword and don't know the need for dual steels (soft on the spine and hard on the edge, it must be REALLY difficult to recreate.

It's not just Differential hardening, but also using different steels in the first place.The exact process might be difficult to figure out (why would one consider using inferior raw materials if not by necessity), but a master blacksmith not being able to notice differential hardening makes no sense.

thanks for the release.
but really, who would believe someone summoned mountains to surround a city?
would have been funny if he mentioned it in letter as a footnote
No, but they are different. They come from a different tradition of forging, which can be a difficult thing to recreate whole-cloth, especially when you're already so far down another path. It even says that they were able to create katana-shaped objects—things that I assume mimicked or even improved upon the shape and properties of the katana—but were still different enough that it did not have the "soul" of the weapon they talk about.Katanas are no harder to forge than any other sword.
