Expression: "He stabbed the sword across his body."

[Tom]

Hi

Would you say that the following sentence sounds OK to you? If no, please help me with it. I hope you understand his action.

[Conchita]

I would either replace 'across' with 'through' or say:

He stabbed himself with the/his sword.

[Tom]

Thanks, Conchita.

I want to say that the man was stabbed so hard in the stomach that the sword came out from his back. How do the following sentences sound to you?

[Yankee]

Hi Tom

I assume that the man did not stab himself, right? How about this:

He skewered his opponent with his sword.
