Kiddi Kutter Childs Safety Knife 5 "Brilliant Preschool Knife" Denise Tupman 05 March 2017 we have two of these which we purchased for our preschool class to use when we make our our smoothies. They are used by our 3 and 4 years olds. Yes they do take a little bit of getting used to as you do have to use a sawing action, to literally saw through the front. Our children love them, they are very safe but of course as with any knife they should still only be used under supervision. We love them, the children love them and so do OFSTED. They are a considered purchase but worth every penny.
