Abstract

A utility tool comprising a body having a first end and a second end positioned on opposite ends of the body; a removable device; as well as a first tool and a second tool configured to be selectively coupled to each other or one of either the first end and second end of the body. The utility tool includes a removable blade cartridge having a blade cartridge body having a recess slot and a knife slot, a knife blade and a guide. The knife blade is positionable within the recess slot and slides between an open position and a closed position.

Claims

1. A removable blade cartridge configured to fit within a corresponding blade cartridge bay, the blade cartridge comprising:

a. a blade cartridge body having a recess slot within and a knife slot in communication with the recess slot;

b. a knife blade having a first end and a second end positionable within the recess slot and configured to slidably move between an open position and a closed position;

c. a guide coupled with the knife blade, wherein the guide drives the knife blade between the closed position and the open position; and

d. a safety spring for applying a first force to the guide when the blade cartridge is disengaged from the blade cartridge bay, wherein the knife blade is prevented from moving when the first force is applied to the guide,

wherein the removable blade cartridge is configured to fit within the corresponding blade cartridge bay in a first configuration with the first end of the knife blade extended when the knife blade is in the open position and a second configuration with the second end of the knife blade extended when the knife blade is in the open position.

2. The removable blade cartridge according to claim 1 further comprising a leaf member for engaging with and disengaging from the blade cartridge bay.

3. The removable blade cartridge according to claim 1 wherein the blade cartridge body further comprises:

a. a first body side; and

b. a second body side in communication and positioned substantially parallel to the first body side, wherein the recess slot is located between the first body side and the second body side, the blade cartridge body including a thin film of material configured over the knife slot such that the knife blade pierces the thin film when moving initially from the closed position to the open position.

4. The removable blade cartridge according to claim 1 wherein the guide is configured to interact with a guide spring when the removable blade cartridge is positioned within the blade cartridge bay, wherein the guide spring urges the knife blade to retract to the closed position.

5. The removable blade cartridge according to claim 1 wherein when the removable blade cartridge is positioned within the blade cartridge bay, the knife blade is moveable between the closed position and the open position.

6. The removable blade cartridge according to claim 1 wherein the guide further comprises a knife switch coupled to the knife blade.

7. The removable blade cartridge according to claim 1 further comprising a thin rib coupled to the blade cartridge body for informing a user of prior use of the knife blade.

8. A removable blade cartridge configured to fit within a corresponding blade cartridge bay, the blade cartridge comprising:

a. a blade cartridge body having a recess slot within and a knife slot in communication with the recess slot;

b. a knife blade having a first end and a second end positionable within the recess slot and configured to slidably move between an open position and a closed position;

c. a leaf member for engaging with and disengaging from the blade cartridge bay; and

d. a guide coupled with the knife blade, wherein the guide drives the knife blade between the closed position and the open position,

wherein the removable blade cartridge is configured to fit within the corresponding blade cartridge bay in a first configuration with the first end of the knife blade extended when the knife blade is in the open position and a second configuration with the second end of the knife blade extended when the knife blade is in the open position.

9. A removable blade cartridge configured to fit within a corresponding blade cartridge bay, the blade cartridge comprising:

a. a blade cartridge body having a recess slot within and a knife slot in communication with the recess slot;

b. a knife blade having a first end and a second end positionable within the recess slot and configured to slidably move between an open position and a closed position;

c. a thin rib coupled to the blade cartridge body for informing a user of prior use of the knife blade; and

d. a guide coupled with the knife blade, wherein the guide drives the knife blade between the closed position and the open position,

wherein the removable blade cartridge is configured to fit within the corresponding blade cartridge bay in a first configuration with the first end of the knife blade extended when the knife blade is in the open position and a second configuration with the second end of the knife blade extended when the knife blade is in the open position.
