The Kershaw Komachi knives may be cute, but the technology and color coding have a serious purpose: stopping cross contamination when preparing food. The fluorinated-resin coating on the high carbon stainless steel blade helps resist bacteria while the color coded, special-function knives help with safety by not using the same knife for all items. The attractive and innovative ergonomic resin handle is see-through, revealing logos for the type of food the knife should be used on.
