No, the name of the weapon is not undetermined. I just couldn't decide which U weapon to write about. You see, I actually took requests/suggestions on this one because I really couldn't come up with anything. And here is what I got:
Uchigatana: A Japenese sword much like the Ninjato or Katana (which I already posted about!)
and last but not least, my personal favorite;
Unicorn. Why is this one my favorite? Because I love mythical creatures and it's true! No really, though Unicorns are myth, they were actually evil. Well in some myths. Most myths depict Unicorns as beautiful, kind, enchanting creatures who heal and protect. But then there are the myths that say Unicorns are evil, disgusting creatures that are beautiful on the outside only to lure people to them before impaling them with their horns.
See? All weapons!
*Disclaimer: I have done extensive research on each of these weapons. I am aware that there are many different versions of each of these weapons. I am not trying to spread false information. If you know and can prove any information wrong, please let me know and I will fix my errors. I have at least three references for all research on the weapons I will discuss through the challenge.
