That's a dumb question, try it irl, I think you'll bleed or cut something of if the sword is sharp enough.

I have had an opportunity to see arterial bleeding, the blood hit the wall behind me which was 3-4 metres away.

Yeah, I've seen someone jumping of the school building with his head first on the ground(suicide and yes he died) there was plenty of blood. He landed partly on a group of girls. Poor girls.

I still think in games it is probably exagerated. But I guess I am glad to not know what I am talking about.

If they wearing bullet proof armor strong enough to deflect bullets than a sword will not even cut down an enemy. But it will cause bruising and other force related injuries.
