This may just save your life

My school is pretty much in the ghetto. Thanks

Then how am I supposed to keep pressure on the wound?

Alternatively, if you're trying to murder someone, take the knife out. Leaving it in will only help them.

Reminds me of the news story where a kid at a party got mad at his friend and threw a steak knife at him. It fly through the air and it lodged in his chest. He panicked and pulled it out. Bled out and died.

I'd push it deeper so it won't fall out....
