According to whom?

The reason why Japanese iron is inferior is because of the source of the iron itself, they utilized iron sand instead of rock ore. Rock ore can be made up to 90% ferrous material while the iron sand contains as little as 2%.

This means when you smelt your source material into blooms of iron and slag, the blooms made from sand iron were much smaller. Instead of utilizing a single bloom to make a sword, the Japanese had to work several blooms together. Which is much more labour intensive, and can lead to a lot of imperfections in the final product.

This is why katanas were made out of so little material, and had to be handled with care. They were much more fragile pieces than similar swords made in Korea and China at the time.

Plus, the Japanese developed their iron working much later than their mainland contemporaries, as they never independently invented furnace technology. The technology for furnaces was imported, most likely from the Korean peninsula.

So i actually saw a video about this recently. Apparently since japan didnt have like any obvious sources to mine iron ore they had to take a bit of an unorthodox approach and collect iron rich sand from streams and waterways. This Iron was more pure than typical Ore but much harder to work with, and form into tools. So their techniques developed differently. Obviously its all the same elements in use at the end of the day. There is a bit of a difference in the way its worked though, and because of that if not made properly the blades can break kind of easily, and when made with proper technique can also be really strong and high quality. So ya basically its both and neither at the same time. Other places also have cheap blades and really nice ones. Just japan gets hyper focused on by certain groups of people.

Also a western sword is an entirely different weapon. Like we see them all as swords but a Katana is something most people can easily pick up while a western sword was like the size of a grown man and very heavy. Because of this western swords just didnt need to be that sharp. The power behind the swing was enough to cut even with a dullish blade. A Katana was more focused on sharpness since its much smaller and didnt have as much weight behind its swings.

In general tho even in japan spears, bows, etc were much more widely used in ancient warfare anyway lol. Swords just became like an iconic thing due to fantasy.

Katana's are weak on the flat side. They aren't really meant to be used for parrying. In fact, most sword fights in Japan would be over after the first or second swing. It was commonplace to hold the grip of a katana but not draw it in such a way so that your enemy has trouble judging how long your katana is and what is a safe distance to be from you. Once your opponent is in range, draw it quickly and kill them in one blow, ideally.

The act of killing your opponent in a single blow is called "nukitsuke" from "nukiuchi" meaning "to cut down an opponent" and "tsuke" meaning "to stop an opponent's attack before it begins".

The Sekiro and popular media image of extended katana fights didn't really happen, but if they did, there would almost certainly be some broken katanas.

I'm not into swords at all but I imagine it's a lot easier to rake the edge of the blade across a surface if it's angled away like a scimitar and more likely to just thwap something perpendicularly with a straight blade. 'Papercut theory' of sorts

Yeah, Japanese steel wasn’t great, but they were working with what they had available at the time. Katanas were basically made out of iron dust, which had been melted into slag by filtering through charcoal. The resulting chunks of steel were basically straight up slag, not nice even ingots. So the steel they got was actually extremely high carbon in places, but that also meant it was brittle as hell, because those carbon pockets were prone to shattering.

So the folding was invented, to even out the steel’s carbon content (just like how a Damascus steel blade has visible stripes, Japanese steel had invisible stripes of high and low carbon steel) and to lower the carbon content overall; Every time you heat for another fold, you’re evaporating some carbon. So the folding process took the steel from extremely high carbon pockets to a more evenly distributed carbon content.

Now that modern steel processing exists, the only real reason to stick to the folding method is tradition. There’s no need to fold modern steel ingots because they’re already homogenous and can be produced at whatever carbon level you want.

Dex build rejoice

It was probably inspired by Egyptian khopesh since it was used in Ethiopia even before the kingdom of Axum. Thing is, the blade is sharp on both sides. So you could either use its inner side as big sickle to reach around enemy shield and try for the weak spots like neck, face or armpits, or if the enemy didn't had a shield you could turn it to outer side and in this case it was similar to Persian shamshir in being excellent weapon against unarmored opponents.

Two more interesting thing about it was 1: the designs varies greatly, most were shorter and wider, the curvature also varied; and 2: it apparently worked quite well considering it has been in use for possibly over 2500 years and some Ethiopian emperors even organised special elite units wielding it.

Blade is around 1 meter long.
