you have some learning to do.

1. nikana is not even a real name of any weapon in real life. therefore this argument shouldn't have been made.

2.  assuming you mixed up nikana and katana, the nodachi/odachi (野太刀) is a type of sword, a type of katana, which is really just 刀. In reality, the word katana just means sword but later on was used as a term to describe a family of swords, which nodachi belonged to.
