20140352156 | CUTTING HAND TOOL - A cutting hand tool which allows easy cutting of thin materials, such as film, paper, packaging or other flexible materials even if the material is folded or stretchy such as shrink- or stretch-wrap, without requiring a strong force, while at the same time protecting the user from injuries. The cutting blade is placed in a recess to prevent accidents and can be rotated or laterally moved by activating a trigger so that an additional force can be applied to cut the material whenever this is required to continue the cutting motion, when the material is rolled over, folded, bunched or reinforced and therefore requires an additional cutting force. | 12-04-2014 |
20140352157 | Utility Cutter - 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. | 12-04-2014 |

20150013171 | Multi-Function Utility Knife - A multi-function utility knife has a housing, a blade seat forward slidably received in the housing, a blade fixed to the blade seat, a driving unit having an actuator protruding out from the housing and an actuator seat reciprocally slidable along the housing, a blade seat return spring linking the blade seat and the housing, a blade change means, and a function switch. The blade of the multi-function utility knife is also able to be either multi-levelly locked when extended or automatically retractable. | 01-15-2015 |
20150328791 | Utility Knife - The utility knife device generally comprises a blade housing covering a portion of the user's hand, including a casing, a blade and a trigger. The blade housing is made up of a casing which preferably encloses the user's index finger, a blade housed within the casing and a trigger which extends out of the casing and manipulates the blade. The blade is capable of extending outward from the casing being held in place for use. The blade is also capable of automatically retracting within the casing so that the blade is not exposed. | 11-19-2015 |
20150336283 | Utility Cutter - 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. | 11-26-2015 |
20160023364 | UTILITY KNIFE WITH BLADE PROTECTOR - The utility knife assembly includes a housing which extends in a longitudinal direction between opposite ends and presents an at least partially open interior. A blade with a sharp edge is fixed with the housing such that the blade extends through one of the longitudinal ends, and the blade is fixed with the housing in such a manner that it is non-movable relative to the housing. A blade protector is partially disposed in the open interior of the housing and is movable in the longitudinal direction relative to the housing between a retracted position and a covering position. In the retracted position, the sharp edge of the blade outside of the housing is exposed for cutting, and in the covering position, the sharp edge of the blade outside of the housing is covered by the blade protector. | 01-28-2016 |
20160031097 | CUTTER ASSEMBLY HAVING A LIMITING STRUCTURE - A cutter assembly has a blade holder, a blade and a limiting element. The blade holder has an elongated blade chamber defined along a longitudinal direction of the blade holder and an opening defined in one end of the blade holder and communicating with the blade chamber. The blade is moveably mounted in the blade chamber. The limiting element is mounted on the blade holder at a position adjacent to the opening and has a limiting segment extending into the blade chamber and abutting a side surface of the blade. | 02-04-2016 |

20160184999 | UTILITY KNIFE WITH PIVOTING HEAD ASSEMBLY - A utility knife is provided that has an elongated main body portion and a head assembly that is separate from the main body portion. The main body portion has a handle assembly. A main body fastening mechanism is provided at one distal end of the handle assembly, and a handle assembly fastening mechanism is provided at one end of the handle assembly. A threaded pin pivotally fastens the main body portion to the head assembly by connecting the main body fastening mechanism to the handle assembly fastening mechanism. Accordingly, the head assembly can pivot with respect to the main body portion and handle assembly, so that the utility knife can be configured to cut an object at different angles, which can be particularly useful for the knife to fit in a tight cutting space. | 06-30-2016 |

20220134584 | SAFETY CUTTING DEVICE - A safety cutting device includes a slidable insert that moves longitudinally within a cavity of a housing. The slidable insert has a cutting blade attached and moves within the housing from a safe position in which the blade is covered to an exposed position for cutting. The safety device has a release button positioned near an anterior end of the housing. A biasing member automatically retracts the blade when the release button is activated. | 05-05-2022 |
