For you Samurai X Fans there is a nice easter egg weapon if you've not noticed.

It is the Sabakato, a reversed bladed Katana which by default does Blunt Damage. It is the only Katana in game that has two functions, blunt and cut damage. It is very interesting to use. I just bought it recently, and normally the color of the sheath just kept me away from it but I broke down I decided to try and use it.

Lets say the blunt ability of it makes it a vastly superior Katana vs say a normal one, being blunt ignores some of the armor rating. So basically you have a very fast blunt weapon vs heavier armored enemies, which you can switch to Cutting whenever you're facing weaker enemies.

If you come across this weapon it will be relatively expensive, a balanced version can range from 5000-7000 mon.
