After seeing one test on 9gag I digged a litte around it, and it turns out that katanas were not that good. Just Hollywood fairy tale. You can find some material on youtube, will not include all the links so that I wan’t share a link to some illegl material, but look around katana vs. longsword key words. I can share these:

There was a test in a german tv show comparing the katana and longsword and it turned out that:

  • Both had similar cutting ability
  • There were a variety of European swords not all meant to stab. Katana can stab, but some European swords can stab better.
  • Katanas were flexible but would not spring back when force that bent them was removed
  • European sword would cut a blade, katana most probably wouldn’t
