Abstract

The present invention generally relates to a wearable cutting device. Specifically, the present invention relates to a cutting device that can be worn over the finger, so that simply by movement of the finger, cutting action may occur upon contact with a surface.

First claim

What is claimed is:

1. A safety cutter ring comprising:
a blade,
a ring shaped body and a blade receiver,
wherein said ring shaped boy includes an opening at each of a front end and a rear end,
wherein the blade receiver is formed on and extends from a bottom side of said ring shaped body and comprises:
a cavity formed within walls of the blade receiver extending from said bottom side of said ring shaped body, wherein said cavity is configured to retain the blade,
wherein said cavity includes an aperture within a bottommost wall of the blade receiver extending from said bottom side of said ring shaped body to allow for the blade to project outwards, away from the ring shaped body,
wherein more than three-quarters of the blade is retained within the cavity,
wherein the blade is fixed at an angle relative to the bottom side of said ring shaped body, and
wherein a portion of the blade projecting outwardly from the cavity is triangular portion.

2. The safety cutter ring of claim 1 , wherein the ring shaped body tapers into the blade receiver at both sides of said ring shaped body, the front end, and the rear end.

3. The safety cutter ring of claim 2 , wherein the front end is of a smaller circumference than the rear end.

4. The safety cutter ring of claim 3 , wherein the aperture is located towards a front end of the blade receiver.

5. The safety cutter ring of claim 1 , further comprising of an insert that fits within a ring shaped cavity of said ring shaped body to accommodate smaller fingers, the insert having a cylindrical body with openings at each end to receive a user's finger.

6. The safety cutter ring of claim 1 , wherein the triangular portion is less than one-quarter of the blade.

7. The safety cutter ring of claim 1 , wherein the blade is formed from ceramic material.

8. A safety cutter ring comprising:
a blade,
a ring shaped body and a blade receiver,
wherein said ring shaped boy includes an opening at each of a front end and a rear end,
wherein the blade receiver is formed on and extends from a bottom side of said ring shaped body and comprises:
a cavity formed within walls of the blade receiver extending from said bottom side of said ring shaped body, wherein said cavity is configured to retain the blade,
wherein said cavity includes an aperture within a bottommost wall of the blade receiver extending from said bottom side of said ring shaped body to allow for the blade to project outwards, away from the ring shaped body,
wherein more than three-quarters of the blade is retained within the cavity,
wherein the blade is fixed at an angle relative to the bottom side of said ring shaped body, and
wherein the blade is disposed at the front end and is angled toward the rear end, the front end having a smaller circumference than the rear end.

9. The safety cutter ring of claim 8 , wherein the ring shaped body tapered into the blade receiver at both sides of said ring shaped body, the front end, and the rear end.

10. The safety cutter ring of claim 9 , wherein the front end is of a smaller circumference than the rear end.

11. The safety cutter ring of claim 10 , wherein the aperture is located towards a front end of the blade receiver.

12. The safety cutter ring of claim 8 , further comprising of an insert that fits within a ring shaped cavity of said ring shaped body to accommodate smaller fingers, the insert having a cylindrical body with an opening at each end to receive a user's finger.

13. The safety cutter ring of claim 8 , wherein the blade is formed from ceramic material.

14. A safety cutter ring comprising:
a blade,
a body including a holding member and a blade receiver member, and
an insert member that is removably disposable in the holding member,
wherein the holding member has an opening at each of a front end and a rear end,
wherein the blade receiver member extends from a bottom wall of said holding member,
wherein a cavity configured to retain the blade is formed within walls of said blade receiver member,
wherein said cavity comprises an aperture within a bottommost wall of said blade receiver member to allow for the blade to project outwards, away from the holding member,
wherein the front end is of a smaller circumference than the rear end,
wherein the blade is angled toward the rear end,
wherein the insert member has a length that is greater than a length of the holding member,
wherein the insert member fits within a ring shaped cavity of the holding member, and
wherein the insert member has an inward-curving middle portion and includes a protrusion disposed on at least one end portion of the insert member.

15. The safety cutter ring of claim 14 , wherein the insert member is formed from a silicone material.

16. The safety cutter ring of claim 14 , wherein the aperture is situated towards a front end of the blade receiver member.

17. The safety cutter ring of claim 14 , wherein the insert member is formed from a cushioning material.

18. The safety cutter ring of claim 14 , wherein the insert member has a cylindrical body with openings at each end to receive a user's finger.

19. A cutting device comprising:
a hollow body;
an insert member that is removably disposable in the hollow body;
a blade receiver; and
a blade;
wherein the hollow body includes an opening at a front end and an opening at a rear end;
wherein the blade receiver is formed on and extends from the hollow body;
wherein a cavity is formed within walls of the blade receiver extending from the hollow body, wherein the cavity is configured to retain the blade;
wherein the blade projects outwards away from the hollow body through an aperture of the cavity;
wherein the front end is of a smaller circumference than the rear end;
wherein the blade is formed from ceramic material;
wherein more than three-quarters of the blade is retained within the cavity;
wherein the insert member has a length that is greater than a length of the hollow body; and
wherein the blade is disposed at a front end of the blade receiver and angled toward a rear end of the blade receiver.

20. A cutting device comprising:
a hollow body;
an insert member that is removably disposable in the hollow body;
a blade receiver; and
a blade;
wherein the hollow body includes an opening at a front end and an opening at a rear end;
wherein the blade receiver is formed on and extends from the hollow body;
wherein a cavity is formed within walls of the blade receiver extending from the hollow body, wherein the cavity is configured to retain the blade;
wherein the blade projects outwards away from the hollow body through an aperture of the cavity;
wherein the front end is of a smaller circumference than the rear end;
wherein the blade is formed from ceramic material;
wherein more than three-quarters of the blade is retained within the cavity;
wherein the insert member has a length that is greater than a length of the hollow body; and
wherein a portion of the blade projecting outwardly from the cavity is a triangular portion.
