Abstract

A jackfruit knife has a blade with generally parallel sides connected at a rounded end. Serrations are present on opposite edges of the blade sides and the rounded end. The blade may be attached to a handle for manual operation, or to an oscillating tool. The motion provided by the oscillating tool reduces or prevents the blade from sticking while cutting into the jackfruit core.

Claims (56)

1. A jackfruit cutting tool comprising:

a blade configured to mount to an oscillating tool drive having:

an attaching portion having a first longitudinal centerline (CL 1 );

a cutting portion extending from the attaching portion having a second longitudinal centerline (CL 2 ), the cutting portion including:

two generally straight and generally parallel sides reaching from the attaching portion;

a closed end connecting ends of the two generally straight and generally parallel sides of the cutting portion, the closed end opposite to the attaching portion;

wherein each of the straight and parallel sides includes a leading edge directcd forward with respect to thc attaching portion and a trailing edge directcd rearward towards the attaching portion;

in a side view, a blade end of the closed end is angled by an acute angle (A 2 ) away from the second longitudinal centerline (CL 2 ) of the cutting portion providing a point of a front edge of the cutting portion; and

the two generally straight and generally parallel sides have serrations on each of their leading and trailing edges; and

wherein the attaching portion includes a flat attaching portion symmetrical about the first longitudinal centerline including a pattern of at least three indentations including one indentation aligned with the centerline (CL 1 ) and at least two indentations laterally spaced relative to the centerline (CL 1 ) and the attaching portion adapted to releasably receive an oscillating tool drive shaft.

2. The tool of claim 1 , wherein:

the closed end includes a closed end front edge opposite to a closed edge rear end; and

end serrations reside on both of the closed end front edge and the closed end rear edge.

3. The tool of claim 2 , wherein the closed end is a rounded end, rounded away from the attaching portion.

4. The tool of claim 1 , wherein:

the second longitudinal centerline (CL 2 ) of the two generally straight and generally parallel sides is angularly offset down from the first longitudinal centerline (CL 1 ) of the attaching portion by an angle A 1 .

5. The tool of claim 4 , wherein the second longitudinal centerline (CL 2 ) of the two generally straight and generally parallel sides is offset from the first longitudinal centerline (CL 1 ) of the attaching portion by the angle (A 1 ) angling down between 45 and 90 degrees.

6. The tool of claim 5 , wherein the two generally straight and generally parallel sides are angularly offset from the attaching portion by the angle A 1 angling down about 60 degrees.

7. The tool of claim 1 , wherein the two generally straight and generally parallel sides are separated by between 40 and 70 mm.

8. The tool of claim 7 , wherein the two generally straight and generally parallel sides are separated by about 40 mm.

9. The tool of claim 1 , wherein the two generally straight and generally parallel sides are between 1.5 and 3 mm thick.

10. The tool of claim 9 , wherein the two generally straight and generally parallel sides are about 2 mm thick.

11. The tool of claim 1 , wherein the two generally straight and generally parallel sides are between 40 and 70 mm wide.

12. The tool of claim 11 , wherein the two generally straight and generally parallel sides are about 40 mm wide.

13. The tool of claim 1 , wherein the two generally straight and generally parallel sides having a length between 150 and 200 mm.

14. The tool of claim 13 , wherein the two generally straight and generally parallel sides having a length of about 175 mm.

15. The tool of claim 1 , further including a continuous permanently unobstructed opening between the two generally straight and generally parallel sides and between the attaching portion and the closed end.

16. The tool of claim 15 , wherein the cutting portion, before bending into a “U” shape, describes a “V” shape.

17. A jackfruit cutting tool comprising: a blade configured to mount to an oscillating tool drive having:

an attaching portion;

a cutting portion extending from the attaching portion and including:

two generally straight and generally parallel sides reaching from the attaching portion, wherein the two generally straight and generally parallel sides include:

serrations on opposite edges;

are angled down at between 45 and 90 degrees from the handle portion;

a length between 150 and 200 mm;

a width between 40 and 70 mm;

thickness between 1.5 and 3 mm;

a separation of between 40 and 70 mm;

a rounded end opposite to the attaching portion connecting the two generally straight and generally parallel sides wherein each of the straight and parallel sides includes a leading edge directed forward with respect to the attaching portion and a trailing edge directed rearward towards the attaching portion;

the rounded end rounded away from the handle portion; and

in a side view, a blade end of the rounded end of the cutting portion is angled by an acute angle (A 2 ) away from a second longitudinal centerline (CL 2 ) of the cutting portion providing a point of a front edge of the cutting portion, and the two generally straight and generally parallel sides have serrations on each of their leading and trailing edges; and

wherein the attaching portion includes a flat attaching portion symmetrical about the first longitudinal centerline including a pattern of at least three indentations including one indentation aligned with the centerline (CL 1 ) and at least two indentations laterally spaced relative to the centerline (CL 1 ) and the attaching portion adapted to releasably receive an oscillating tool drive shaft.

18. A jackfruit cutting tool comprising:

a blade configured to mount to an oscillating tool drive, the blade having:

an attaching portion having an oscillating tool pattern common to oscillating tool blades configured connect the attaching portion to an oscillating tool;

a cutting portion comprising:

two generally straight and generally parallel sides reaching from the attaching portion end, wherein each of the straight and parallel sides includes a leading edge directed forward with respect to the attaching portion and a trailing edge directed rearward towards the attaching portion; and

wherein the two generally straight and parallel sides include:

an angle down of 60 degrees from the handle end;

a length of 175 mm;

a width of 40 mm;

a separation of 40 mm;

a thickness of 2 mm;

a closed end opposite to the attaching portion and connecting the two generally straight and generally parallel sides; and

in a side view, a blade end the closed end is angled by an acute angle (A 2 ) away from a second longitudinal centerline (CL 2 ) of the cutting portion providing a point of a front edge of the cutting portion, and the two generally straight and generally parallel sides have serrations on each of their leading and trailing edges; and

wherein the attaching portion includes a flat attaching portion symmetrical about the first longitudinal centerline including a pattern of at least three indentations including one indentation aligned with the centerline (CL 1 ) and at least two indentations laterally spaced relative to the centerline (CL 1 ) and the attaching portion adapted to releasably receive an oscillating tool drive shaft.
