Every knife can bypass stabproof vests with enough force, but that's beside the point. The knife is designed to bypass skin and flesh, hence the potential for abuse. You go down that path and you end up with the insane knife laws Western Europe has where just carrying a swiss army knife with you can be illegal. They do practically nothing for knife crime (as shown by knife crime statistics), but they sure create a lot of busywork for the police to show up on their performance reports.

By the way, you ever go to the gym? What do you need all those muscles for? Maybe to be able to stab through stabproof vests?
