Abstract

A knife including a blade section having a sharp edge, a J-shaped section, and a handle section connected to the J-shaped section. The J-shaped section may have a bottom portion connected to a stem portion, and a substantially uniform thickness. The sharp edge may have a thickness which is substantially less than the substantially uniform thickness of the J-shaped section. The handle section may have a thickness which is substantially greater than the uniform thickness of the J-shaped section. The blade section, the J-shaped section, and the handle section may be configured so that a person can place an index finger of the person so that an end of the index finger contacts the bottom portion of the J-shaped section and a length of the index finger contacts the stem portion of the J-shaped section, while simultaneously one or more further fingers of the person grip the handle section.

Claims (45)

1. A method comprising

using a knife to pare an outer covering off of an object using a sharp edge of the knife;

wherein the knife includes:

a blade section having a sharp edge;

a J-shaped section adjacent the blade section;

a handle section connected to the J-shaped section;

wherein the J-shaped section has a bottom portion connected to a stem portion;

wherein the J-shaped section has a substantially uniform thickness;

wherein the sharp edge has a thickness which is substantially less than the substantially uniform thickness of the J-shaped section;

wherein the handle section has a thickness which is substantially greater than the uniform thickness of the J-shaped section;

wherein the blade section, the J-shaped section, and the handle section are configured so that a person can place an index finger of the person so that an end of the index finger contacts the bottom portion of the J-shaped section and a length of the index finger contacts the stem portion of the J-shaped section, while simultaneously one or more further fingers of the person grip the handle section;

wherein the sharp edge of the blade section has a first end and a second end;

wherein the first end of the sharp edge of the blade section is further from the handle section than the second end of the sharp edge of the blade section;

wherein the bottom portion of the J-shaped section is closer to the first end of the sharp edge of the blade section than the second end of the sharp edge of the blade section;

wherein the bottom portion of the J-shaped section has a first end directly connected to the stem portion of the J-shaped section and a second end which is directly connected to a first end of a substantially straight surface; and

wherein the substantially straight surface has an opposing second end which is directly connected to the first end of the sharp edge of the blade section.

2. The method of claim 1 wherein

the bottom portion of the J-shaped section is substantially parallel to at least part of the sharp edge of the blade section.

3. The method of claim 1 wherein

the bottom portion of the J-shaped section is substantially perpendicular to the stem portion of the J-shaped section; and

the sharp edge of the blade section curves from a first end where the sharp edge is substantially parallel to the bottom portion of the J-shaped section to an opposing second end where the sharp edge is substantially parallel to the stem portion of the J-shaped section.

4. The method of claim 1 wherein

the knife includes an intermediate section connected between the blade section and the handle section;

wherein the intermediate section has a curved surface;

wherein the J-shaped section is on one side of the knife and the curved surface of the intermediate section is on an opposing side of the knife;

wherein the curved surface of the intermediate section has a substantially uniform thickness which is substantially greater than the thickness of the sharp edge;

wherein the curved surface of the intermediate section and the J-shaped section are configured so that an end of an index finger of a person can contact the bottom portion of the J-shaped section while a further finger of the person contacts the curved surface of the intermediate section.

5. The method of claim 1 wherein

the bottom portion of the J-shaped section is substantially perpendicular to the stem portion of the J-shaped section; and

the sharp edge of the blade section curves from a first end where the sharp edge is substantially parallel to the bottom portion of the J-shaped section to an opposing second end where the sharp edge is substantially parallel to the stem portion of the J-shaped section.

6. The method claim 1 wherein

the substantially uniform thickness of the J-shaped section is about one eighth of an inch or greater.

7. The method of claim 1 wherein

the thickness of the handle section is about three times the thickness of the J-shaped section.

8. The method of claim 1 wherein

the knife is elongated, such that the knife has a length and a width, and the length is substantially greater than the width;

and wherein the length is about six and one half inches, and the width is about one and one quarter inches.

9. The method of claim 1 further comprising

applying force with the end of the index finger to the bottom portion of the J-shaped section without the end of the index finger being cut or pinched in order to use the knife to pare the outer covering off of the object using the sharp edge of the knife.

10. The method of claim 1 wherein

the bottom portion of the J-shaped section is an indentation of the blade section opposite the sharp edge of the blade section.

11. The method of claim 1 further comprising

using the index finger to apply force to the J-shaped section while the end of the index finger contacts the bottom portion of the J-shaped section and the length of the index finger is substantially straight in order to use the knife to pare the outer covering off of the object using the sharp edge of the knife.

12. The method of claim 9 further comprising

using the index finger to apply force to the J-shaped section while the end of the index finger contacts the bottom portion of the J-shaped section and the length of the index finger is substantially straight in order to use the knife to pare the outer covering off of the object using the sharp edge of the knife.
