A British company will sell knives with square tips after a sharp rise in knife crime

Nothing new here. In days of iron men sailing wooden ships, each crew member brought his own knife and if it had a sharp tip, the boatswain would break it off. Why? For the same reason the Brits are making knives with square tips. Will it help? Hell no...

So in a minute I can grind in a minute!

MSgt (Join to see), this has been going on since 1637, when Cardinal Richelieu invented the table knife. Then, “In 1669, King Louis XIV of France banned pointed knives – at the table and as weapons – to try put an end to the culture of violence of the time. This further cemented the position of the round-ended table knife as preferred form of cutlery.”
Not really making light of your observations. I agree with you about the alien travel ban!
