Abstract

An embodiment includes a cutting device having a blade; a device architecture configured to hold the blade that includes: a pressure body operable to remain rigid in response to a substrate pressing against a portion of the pressure body at a first pressure, and a portion of the pressure body operable to deform in response to the substrate pressing against a portion of the pressure body at a second pressure, and thereby provide variable resistance against the substrate; and, a cutter slot at a first device architecture end defined by the blade and the pressure body, the cutter slot configured to receive the substrate and operable to open rearwardly toward a second end as the pressure body deforms.

Claims

1. A cutting device comprising:

a blade;

a device architecture configured to hold the blade comprising;

a pressure body comprising a spring extension and operable to remain rigid in response to a substrate pressing against a portion of the pressure body at a first pressure, and a portion of the pressure body operable to deform in response to the substrate pressing against a portion of the pressure body at a second pressure, and thereby provide variable resistance against the substrate; and

a cutter slot at a first device architecture end defined by the blade and a pressure arm of the pressure body, the cutter slot configured to receive the substrate and operable to open rearwardly toward a second end as the pressure body deforms;

wherein the spring extension extends from a portion of the device architecture at a first spring extension end in a first direction;

wherein the pressure arm extends from a second spring extension end in a second direction substantially opposite from the first direction; and

wherein the spring extension and the pressure arm define a pressure body slot; and

wherein the cutter slot is defined within the pressure body slot.

2. The cutting device of claim 1, wherein the spring extension is operable to deform in response to the substrate pressing against the portion of the pressure body at the second pressure.

3. The cutting device of claim 1, wherein the pressure arm is operable to move in response to the substrate pressing against the portion of the pressure body at the second pressure.

4. The cutting device of claim 3, wherein the pressure arm is operable to move into a lower cavity defined by the device architecture.

5. The cutting device of claim 1, wherein a portion of the pressure body resides within an upper cavity defined by the device architecture, and wherein a portion of the pressure body is operable to contact a portion of the device architecture defining the upper cavity as the pressure body deforms and thereby provide further variable resistance to the substrate.

6. The cutting device of claim 1, wherein a portion of the pressure body is operable to reside within an lower cavity defined by the device architecture, and wherein a portion of the pressure body is operable to contact a portion of the device architecture defining the lower cavity as the pressure body deforms and thereby provide further variable resistance to the substrate.

7. The cutting device of claim 1, wherein the pressure body is contiguously formed from the device architecture.

8. The cutting device of claim 1, wherein the pressure body is a discrete body held within a portion of the device architecture.

9. The cutting device of claim 1, wherein the pressure body defines a blade slot, wherein a portion of the blade is operable to reside therein.

10. The cutting device of claim 1, wherein the blade is removable from the device architecture.
