| Stage | Knife | What they cut | Watch for |
|---|---|---|---|
| Around 2-3 | Nylon / plastic knife | Bananas, strawberries, soft bread | Too dull frustrates; short useful life |
| Around 3-5 | Rounded guard-edge steel | Cucumbers, tomatoes, soft vegetables | Still a knife — side-by-side always |
| From about 6 | Small real knife (petty, junior santoku) | Real prep with the claw grip | Teach board stability and slow cuts |
| Any age | Adult knives, unsupervised | Nothing | The one option that's never right |
Which Kids' Kitchen Knife for Which Age?
Published: ·Updated:
Match the blade to the age: a nylon knife for 2-3 year olds cutting bananas, a rounded-edge steel kids' knife once real vegetables enter around 3-5, and a small true-edge knife from early grade school. All of it side by side with an adult — the knife choice never replaces the supervision.
