Every human I have ever met knows what a katana is and hold some kind of deep reverence and mystique for it.
Pretty much everyone I know could not name a single Chinese blade.
Pretty much everyone I know has a vague awareness of swords that are long that knights used and they are called long swords or something. Most people have also heard of a Bowie but argue over how to pronounce it.
This is a weird situation given European blade culture is the most developed, proven and dominant force in human history. Europeans where in a literal arms race against everyone forever and as a result crafted the most developed and successful skills and weapons.
Japan on the other hand used their blades to cut up live sea animals, had almost no wespons development and used the katana mainly to bully a few defenceless peasants and occasionally self snuff the operator.
China has possibly the longest blade history, development, mythology and not even the Chinese know about it unless it is a Kung Fu demo in the mall on Chinese New year.
Why the katana so highly entrenched in the entire psyche of the world when it is basically a crow bar with an edge that has done little more than harm defenceless people.
Everything said is totally well researched and unbiased facts.... totally.
