Grapefruit Knife FAQ
Why is a grapefruit knife curved?
The curve follows the shape of the fruit so you can cut along the rind.
Can I use a grapefruit knife on oranges?
Yes, it works on other citrus as well.
Are grapefruit knives sharp?
Serrated edges are designed to cut pulp, and the blade can still cut skin. Handle it with care and keep it away from small children.
Do I need a grapefruit spoon too?
Many people use both. The knife frees the segments and the spoon scoops them out.
The Short Version
For a trusted brand, Victorinox. For a simple option, Norpro. For heavy use, Dexter-Russell. For a basic blade, Chef Craft. For a small tool, Fox Run. For an easy grip, Zyliss. Any of them will do the job if the blade is curved and serrated. Pick the handle that feels best when your hands are wet, and keep the knife for fruit only so the teeth stay in good shape.
