The Mac kid's knife was designed to provide children with a truly functional knife that has several safety features to maximize safety. The blade is constructed of Mac's molybdenum stainless steel and is quite sharp along the cutting edge. However the tip and heel of the knife have been rounded and dulled to prevent accidental nicks. The handle is oval and thin for small hands, and made of Lamar resin, which is both comfortable and slip-resistant. There is a hollow area designed for the index finger to make it easy for a child to apply the proper downward cutting pressure. Blade length is 5 inches, with a handle length of 4 inches. Of course, these should be used with adult supervision, but this is an excellent way to introduce children to the fine are of cooking in the safest possible manner. We highly recommend this product.
