Abstract

A landscape utility knife assembly discloses a single tool that can puncture the middle of a landscape liner and make the incisions necessary to place plants in the middle region of a landscape or garden area. The knife assembly consists of a replaceable blade and housing. The housing is composed of three regions: a handle region, a blade region, and a penetration region. These regions, which compose the housing, are arranged geometrically to form an acute angle. The tip of the penetration region forms a sharp point that can puncture a landscape liner. The penetration region is adjacent to the blade region and serves also to guide the liner into the replaceable blade that is exposed and recessed at the vertex of the angle formed by the housing.

Claims

1. A method of cutting landscape liners, which comprises:

providing a landscape utility knife having a cutting blade and a housing, the housing configured to have a penetration point; and

penetrating a landscape liner with the penetration point of the landscape utility knife; and

cutting a slit adjacent to the puncture in the landscape liner with the cutting blade of the landscape utility knife.

2. A method of cutting landscape liners, as recited in claim 1, wherein the landscape utility knife has a replaceable blade.

3. A method of cutting landscape liners, as recited in claim 1, wherein the landscape utility knife has a handle region, a blade region, and a penetration region, wherein together the handle region, the blade region, and the penetration region form an acute angle.

4. A method of cutting landscape liners, as recited in claim 3, wherein the landscape utility knife has a replaceable blade.

5. A method of cutting landscape liners, as recited in claim 4, wherein the penetration region extends from the blade region, the penetration region having a point at a tip of the penetration region to form the penetration point, the tip being sufficiently sharp to penetrate the landscape liner.

6. A method of cutting landscape liners, as recited in claim 1, wherein the landscape utility knife has a penetration region extending from a blade region, the penetration region having a point at a tip of the penetration region to form the penetration point, the tip being sufficiently sharp to penetrate the landscape liner.

7. A method of cutting landscape liners, as recited in claim 1, wherein the landscape utility knife has a handle region that is ergonomically designed.

8. A method of cutting landscape liners, as recited in claim 1, wherein the landscape utility knife has a removable covering on one side of a blade region, the removable covering attached to the landscape utility knife housing by a fastening mechanism.

9. A landscape utility knife for cutting landscape liners, which comprises:

a blade;

a landscape utility knife housing;

a handle region formed as part of the landscape utility knife housing;

a blade region formed as part of the landscape utility knife housing;

a penetration region extending from the blade region and forming a point at a penetration region tip sufficiently sharp to penetrate a landscape liner;

wherein the handle region, the blade region, and the penetration region form an acute angle.

10. The landscape utility knife of claim 9, wherein one side of the blade region contains a removable covering attached to the landscape utility knife housing with a fastening mechanism that secures the blade in the landscape utility knife housing.

11. The landscape utility knife of claim 10, wherein the blade is replaceable.

12. The landscape utility knife of claim 9, wherein the blade is replaceable.

13. The landscape utility knife of claim 9, wherein the handle region is ergonomically designed.

14. The landscape utility knife of claim 9, wherein the handle region contains a hollowed region on the end opposite the blade region.

15. The landscape utility knife of claim 9, wherein the landscape utility knife housing is shaped to resemble a head of a bird.

16. A utility knife for cutting materials, which comprises:

a replaceable blade;

a utility knife housing;

a handle region formed as part of the utility knife housing;

a blade region formed as part of the utility knife housing; and

a penetration region extending from the blade region and forming a point at a penetration region tip sufficiently sharp to penetrate a material,

wherein the handle region, the blade region, and the penetration region form an acute angle, and

wherein one side of the blade region contains a removable covering attached to the utility knife housing by a fastening mechanism.

17. The utility knife of claim 16, wherein the handle is ergonomically designed.

18. The utility knife of claim 16, wherein the handle contains a hollowed region on the end opposite the blade region.

19. The utility knife of claim 16, wherein the utility knife housing is shaped to resemble a head of a bird.
