I purchased this along with several other swords. Bottomline: you can really hurt someone or yourself with this weapon. However, if you plan on doing some sword battle with a couple of Samurai...you will definitely need either a better sword, or a 30 yard head start. But do not believe reviews that criticize this sword and it's sharpness or capabilities to do harm. It's sharp enough and will give even a novice an opportunity to train with something decent. If you want more "authenticity", you're going to have to reach into your wallet and pay a heck of a lot more.
