For their children this knife is certainly useful, but probably not for some anxious parents!
Buy it for children nor a finger to protect (eg Jamie Oliver JB7900 finger guard, black)
Explain to your child the right work equipment and the danger of sharp edge.
Do not leave your child. Children should of course have learned to deal with knives, so not for young children!
My daughter is now seven years and has helped with this knife successfully and without injury, work up fresh meat on a farm. By sharp edge makes working with this knife and the kids fun!
Conclusion: full purchase recommendation
PS: Dull knives are dangerous as working with greater force!
