The Kai Luna Citrus Knife makes a handy addition to your kitchen collection. The small serrations on the blade of this attractive knife cut through the tough, thick skins of lemons, limes, oranges, grapefruit, and more with ease. It works beautifully for cutting around the membrane between grapefruit segments for easier eating. If you enjoy making cocktails, a citrus knife is a must-have for the home bar.
