title: "Which Kids' Kitchen Knife for Which Age?"
lead: "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."
recommendation:
  name: "A rounded-edge steel kids' knife around age 3-5, skipping long nylon detours"
  reason: "The 'can't-cut-hands' guard-edge steel knives are the sweet spot: sharp enough that a tomato doesn't require dangerous force, blunted and tip-rounded enough that slipping fingers get a scare instead of a cut. Nylon knives are a fine first month for banana-and-strawberry work but frustrate kids quickly — and a knife that needs force is its own hazard. From around six, graduate to a small real knife (a petty or junior santoku) and teach the claw grip; guard-edge knives teach motion, real knives teach respect. Every stage is a two-person activity."
