What if we let children use knives and other sharp tools?

Reasons to give your child a kitchen knife (and teach them how to use it), which I agree with for the same reasons, from the following article:

1. Independence
2. Invested in food
3. It's what we used to do as a civilization! (We already know it can be done safely, you don't hear about accidental kitchen accidents among children from the 1800s).
4. Trust
5. Taking risks and learning consequences
6. Pride
