And, FWIW, I don't ... for a solitary second, believe Krystal had a potato knife with her! It's so small ... Hobbs already left the house to look for her in a foul mood ... and his rage was in motion by then. I speculate he grabbed that knife on reflex, as he strode off in fierce search of his daughter (having no idea Krstal was with her).
I'd further speculate that RATHER than Krystal reaching for the knife ... she tried to run away and this ... this ... this monster swung around and caught her. If he 'said' and 'wrote' in his statements to police that Krystal brought out the knife, I certainly do not believe him. And I'll never believe him UNLESS Krystal's family confirm she had a knife on her.
Rage, rage, rage. Uncontrollable rage by a demented monster. A coward who brutally attacks children, women and old people (as proved by the attack on his spouse's mother... the chainsaw incident.) Ugh!
