Review on Fox Run 6601 Grapefruit Knife: Premium Stainless Steel & Plastic, 7.75 x 1.25 x 1.25 inches by Chinelo Aranjo

I learned how to use those cheap, single-edged, curved, serrated grapefruit tools as a kid, but this one is way better because it has a dual blade that lets you cut BOTH sides of the Membrane can cut at once. When used correctly, you can easily and quickly "slice" a grapefruit (or orange) into easy-to-open pieces. (And you can always squeeze the juice afterwards.) Remember to brush between the blades each time you're done, as the springy action will grab the pulp.
