How to properly hold your knife?

You don't hold your knife with just any hand
We do not change hands during the meal
We don't grab it vulgarly
We never lick it to wipe it away
We don't put it on the tablecloth

But then, how do we use it?

The knife is held in the right hand
It is normally held by the end of the handle, without touching the blade with the finger
Place it on the knife holder to avoid stains on the tablecloth
