You are correct, so uses are. Just as using a rosary to strangle a person would be intrinsically evil.
A priest’s stole could be used to hang a person
But it does not follow that the rosary nor the stole themselves are intrinsically evil because they could be put to evil uses. What the Church considers to be the evil act is NOT the object, but the intent and the action.
That is why the Church does not even consider condoms to be instriscally evil, but rather their contraceptive use. If someone uses a condom to keep matches dry (as they did in WW-II), then there is no moral fault.
Likewise, if a gun is used in self defense, there is no moral fault, no evil act, intrinsic or otherwise was committed.
This is basic Catholic Moral Theology, I am surprised that you have such a lack of understanding on it.
