>>509949727 (OP)It means he didn't just grab a knife.
He had to specifically pick the knife.
It's like how a case that could go as a crime of passion or self defense gets tried as pre-meditated murder because the killer reloaded their gun and shot again.
The moment you actively work to kill someone, it's pre-meditated. And pulling the knives out of these fucking thing requires active work.
This is because the manufacturers don't want to be sued by someone whose utility knife opened up without resistance and sliced their fingers.
The only other option is that he modified it so the knife slips out easier, which then makes it pre-meditated since he modified the knife beforehand.
