Abstract

Pocket safety cutter devices include ergonomic blade housing and handle portions adapted to be safely folded together into compact closed configurations.

Claims

1. A pocket knife comprising:

a housing including an opening to a channel within the housing;

a blade carrier within the channel, the blade carrier including one or more actuator portions that permit a user of the pocket knife to slide the blade carrier along the channel;

a spring operatively connected between the blade carrier and the housing such that the blade carrier is biased along the channel toward a blade retracted position; and

a handle pivotally connected to the housing, the handle including a recessed portion sized to receive the housing when the housing is pivoted toward the handle;

wherein the housing includes a main portion and a front end portion that is pivotally secured to the main portion such that the front end portion can be moved to gain access to the blade carrier.

2. The pocket knife of claim 1, further comprising:

a blade mechanically coupled to the blade carrier.

3. The pocket knife of claim 1, wherein the housing includes a front end portion that includes a protrusion adjacent to the opening, the protrusion being received within the recessed portion when the housing is pivoted into the handle to a pocket knife closed position.

4. The pocket knife of claim 3, wherein the protrusion is fin-shaped.

5. The pocket knife of claim 1, wherein the housing includes one or more slots through which the one or more actuator portions extend.

6. The pocket knife of claim 5, wherein the one or more slots include two slots located on opposite sides of the housing.

7. The pocket knife of claim 5, wherein the housing is shaped such that a portion of the housing that includes the one or more slots extends from the recessed portion when the housing is pivoted into the handle to a closed position.

8. The pocket knife of claim 1, wherein the front end portion is a die-cast assembly that includes a screw.

9. The pocket knife of claim 1, wherein the one or more actuator portions include two actuator portions.

10. The pocket knife of claim 1, wherein the housing and the handle each include complementary exterior surfaces that provide the pocket knife with a profile shape that is substantially symmetrical when the housing is pivoted into the handle to a closed position.

11. The pocket knife of claim 1, wherein the housing and the handle each include complementary exterior surfaces that define a curved top edge of the pocket knife when the housing is pivoted out of the handle to an opened position.
