There are a lots better stabbing instruments than a box cutter, a box cutter is a slashing instrument. Dumb criminal Mexican.
box cutters killed over 3000 people not so long ago
If you are arrested and frisked, you can argue that a box cutter is a tool for opening boxes, not a weapon. It's also cheap enough that you can toss it if you think you might soon meet up with the police. Meanwhile, hardly anyone wants to risk getting cut with one.
My grand nephew Mark Adam Holdren was murdered by an illegal alien with a box cutter.
