Benefits of technology

The design reduces the risk of injury by ensuring the blade is enclosed during non-use and allows for efficient cutting of various materials with automatic blade extension and retraction, saving user energy and increasing safety and productivity.

Problems solved by technology

Utility cutters, however, may be actuated accidentally even during periods of storage or non-use.
Accidental actuation of a utility cutter, therefore, may present a substantial hazard to the user, other persons, or valuable material.

Embodiment Construction

[0051]The figures and following description illustrate and explain a utility cutter 100, which may be used to cut rigid or semi-rigid materials, such as, for example, corrugated board, cardboard or other paper products, rubber, plastic, Styrofoam, or any other appropriate material. The utility cutter 100 is typically a handheld device operated by either a left-handed or right-handed user with equal ease. In some implementations, the utility cutter 100 allows the user to carry, transport, or otherwise handle the cutter 100 in a safe position, whereby a sharpened blade of the cutter 100 is enclosed or substantially enclosed within a protective housing or handle. The user may, as appropriate, engage the cutter 100 into a material by engaging a guide attached to the blade into the material. Once engaged, the guide may extend the blade from the housing to expose a cutting edge of the blade to the material. Once the user finishes cutting the material as desired, the user may disengage the...

Abstract

A knife includes a handle that includes a gripping surface; a blade slide positioned in a recess of the handle that extends from an opening of the handle through a cavity within the handle; a blade coupled to the blade slide near a proximal end of the blade and extending through the recess and into the opening when the blade slide is in the retracted position; and a guide coupled to the blade near a distal end of the blade opposite the proximal end, the guide including a contoured surface configured to engage a workpiece to extend the blade slide a distance from the retracted position to an extended position such that the blade is extended from the opening of the handle, the blade slide biased to move from the extended position to the retracted position.

Description

TECHNICAL BACKGROUND[0001]This disclosure relates to cutting rigid and semi-rigid materials.BACKGROUND[0002]Utility cutters may be used to cut or slice a variety of materials, such as cardboard, corrugated board of varying thickness, rubber, lightweight plastic, or other packaging material. In order to cut or slice such material, the utility cutter may need to have a sharpened blade. Certain precautions may be used to protect or help protect a user from the sharpened blade. For example, a utility cutter may include guards that extend from the cutter alongside the sharpened blade, such that the guards substantially prevent an accidental injury to the user or other bystander. Further, a utility cutter may include a protective handle that encloses substantially all of a blade during periods of non-use. Utility cutters, however, may be actuated accidentally even during periods of storage or non-use. Accidental actuation of a utility cutter, therefore, may present a substantial hazard to...
