A final suggestion: remove and hide the butcher block and other immediately available objects/weapons that she can seize while in a blind rage. A teen difficult child in a full rage, especially when being thwarted after they've come to expect to have their way, is capable of unthinkable things. It's best to remove anything that she can seize in a moment of rage and use to do something that can literally ruin or even end lives. When I did my "bouncer" gig at my sister's house, we did this and it paid off: I was attacked with various objects--whatever came to hand for the difficult child while enraged--but never with a knife or anything that could really hurt me--because we had removed them all. An ounce of prevention can be immeasurably valuable in this circumstance.
