| Abstract: |
A grapefruit knife for use in cutting sections of edible fruit from the less desirable membrane and peel is disclosed. The present invention includes a handle having two opposing ends, a single cutting blade attached to one end of the handle, and a scooping blade attached to the other end of the handle. Each of these blades has two cutting edges. On the cutting blade the two cutting edges are aligned serially, in a plane, to cut in the same direction, while on the scooping blade the cutting edges are opposingly arranged.

First Claim:
Show all 3 claims |
What is claimed is:
1. A knife for preparing citrus fruit comprising:
- an elongated, hand-graspable handle member having opposite end regions, said handle member being transversely thickened in a portion of each of said opposite end regions;
- first and second blade members, each one connected to a different one of said opposite end regions and extending outwardly in generally opposed relationship to each other;
- said first blade member having a first stem portion adjacent to said handle member and having a flattened elongated first blade portion projecting from and connected to said first stem portion;
- said first blade portion being longitudinally bifurcated so as to define first and second elongated blade sections that are in adjacent, transversely spaced, parallel relationship relative to each other with a slotted gap therebetween;
- said first blade section having a first cutting surface extending along an outside edge portion thereof;
- said second section having a second cutting surface extending along an inside edge portion thereof;
- said second cutting surface being generally in adjacent spaced parallel relationship to said first cutting surface so that said first and said second cutting surfaces cut in the same direction;
- said second blade member having a second stem portion adjacent to said handle member and having an elongated, longitudinally and transversely curved second blade portion projecting from and connected to said second stem portion;
- said second blade portion having:
- a transversely broadened base region adjacent said second stem portion whose width approximates the width of a citrus fruit segment;
- an outermost terminal pointed region; and
- opposed side edges that symmetrically taper from said base region to meet at said pointed region;
- said opposite side edges each having a cutting surface extending therealong;
- said second stem portion having a configuration such that said base region is offset from said handle member;
- said second blade portion having defined therein a first angle adjacent to said second stem portion and relative to said handle member and a second angle adjacent to said base region that inclines said second stem portion relative to said curved second blade portion; and
- said second blade member having a relatively small aperture means defined therethrough in the region where said second stem portion and said second blade portion so connect.
