#19 – Plastic Knives
Plastic knives and other plastic cutlery always come in handy when you are expecting a lot of guests at your home. Unlike metal cutlery, which you need to wash after it is used, you don’t have to wash plastic cutlery, you just throw it away. Plastic cutlery is also safe cutlery, especially for kids.
However, one school in England actually banned plastic knives in its cafeteria. The headmaster of that school probably thought that the kids would stab each other with plastic knives.
