Made for little days

Helping without the fear
They beg to help, but a real chef's knife is a hard no. Serrated plastic knives cut soft foods like cucumber and tomato, with you right beside them.

Sized for small hands
Knives run 7.7 to 10.6 in (19.5 to 27 cm) and weigh 20 to 40 g. Start with 3 pieces, or get 8 with a board, peeler and crinkle cutter.

A real job at dinner time
Give them a cucumber and their own board while you cook. They chop, you stir, and the counter stops being a tug-of-war.

Questions
Good to know

Can my child use it alone?
No. Use it with an adult right beside them every time, and keep the peeler and crinkle cutter in adult hands or guide them hand-over-hand.
