It is! I think you should report it.
Puukko is type of knife though.
Okay so how do i report it??
Use the small flag symbol which is in the red banner telling you your answer was wrong. Similarly, from the green "correct answer" banner you can report accepted answers that are in fact incorrect and shouldn't be accepted.
...and a fork? Maybe she is a waitress?
