a handmade weapon made out of the only stuff you recieve in prison, sharpened to perfection. essentially made out of toothbrushes and spoons.
When we was rioting in the joint and the pigs came to stop us, I busted out my prison shank and killed those mo' fuckin 5-0's

Get the prison shank mug.
Because even in the most restricted enviroment, humans will still find a way to kill each other.
I made a prison shank back in 08 after getting verdict of "guilty."
Apparently some other inmate stole it, because it was gone the next day.
