The Splayed Fork (AA5527) is a combined fork and spoon and the Nelson Knife is a combined knife and fork. Both are designed to help with one-handed eating. The Small Rocker Knife is for cutting food with minimal rocking movement and can be used in the double-ended cutlery handles to make one utensil more versatile. The Large Rocker Knife has a broad semi-circular blade which is ideal for preparing larger food without cocking the wrist.
