Are these 10 things machines or tools?

1. Cell phone 6. Toilet
2. Car 7. Meat Slicer
3. Coffee Maker 8. Knife
4. Computer 9. Calculator
5. Dishwasher 10. Vacuum Cleaner

Tools are handheld devices using manual energy to perform useful tasks and machines are combinations of parts that convert energy into a a more useful form. By that definition, I would consider all of the above to be machines except number 8. In modern day usage however, machines are sometimes called tools like "A vacuum cleaner is a better tool to get sand off the floor than a broom."
