Sword
Katana
noun
The kanji and the word are exactly the same. That means they share meanings as well!
かたな
Since this word is made up of a single kanji, it uses the kun'yomi reading. I'm hoping you already know this word - that will make everything much easier. It's かたな (you know what a katana is, right?).
あのさむらいに、刀をぬすまれたんだ。
My sword was stolen by that samurai.
あのアメリカ人は刀を二ほんもっている。
That American has two katanas.
スラリと刀をぬいたあのおとこはだれだ？
