Well, obviously they just need to root out that reactionary "kitchen culture" from their society. Who needs to cook at home anyway, when there are restaurants on almost every corner?
If you want to use knives, you should go to school and become a licensed chef. Restaurants should have locked cabinents where the knives are stored. When the chef needs to cut a piece of meat, s/he can call a police officer to come unlock the cabinet - or better yet just store the knives at the police station and the chef can walk down there and fill out a multi-page form explaining why s/he needs a knife at that moment.
