Re: Make it like owning a vehicle
"Yes, all blades. If it can cut, is made of metal, then its included."
The knives the Westminster bridge attackers were ceramic, not metal. Presumably they chose them to pass metal detection before they chose their improvised attack. Bought from Lidl. They are a lot more brittle than the kind of knives most killers use but the post-attack photos of them show none of them snapped.
This is maybe too much information since I was only objecting to the "is made of metal" comment. I'll delete this comment if anyone asks me to.
