Our boy, to be 5 years old in September is shaping up to get ready for his first knife
Today he qualified by slicing bread, buttering it, and making a ham sandwich for breakfast in bed to his mother :-)
We have let him use butter knives, and cutting veggies and fruit since he could hold a knife. Think about it. What tool do you use every single day of your life?
It's an important life skill as learning how to dress yourself, tieing your shoe laces and how to ride a bicycle.
And now our boy has shown that he have the necessary motoric skills needed to wield a knife. So he will get one this summer, when we have done some training on whitling.
To be used and carried only under supervision of course...at least until age 6 :-)
