Anyone with a functioning hand and a piece of scrap metal can make a knife. Two functioning hands makes it easier. You don’t even need tools... If you are patient, you can grind it out and sharpen it on a brick or on a cement sidewalk.
Brits are silly. British politicians are even more silly than their peasants.
Brits talk about banning knives. Americans have a game show to make knives, swords, axes, etc.
I thought the same. With a grinder , charcoal , hammer and chunk of iron I could probably make a nasty one myself.
I can’t decide if the real reason is they believe their own nonsense or they want to demean and eviscerate the populace, show them how helpless they are. How they must depend on the nanny state for protection.
