Patent number: 11207790Abstract: An out-the-front knife comprises a handle having a blade channel, a slider channel, and an insert channel interposed between them. A blade in the blade channel and a firing mechanism in the slider channel configured to extend and retract the blade. The blade comprising a blade insert configured to contact the firing mechanism. The firing mechanism comprises a front slider arm, a rear slider arm, a front lock, and a rear lock. When the blade is in the open position, the blade insert is biased against the front slider arm and the front lock and when the blade is in the closed position, the blade insert is biased against the rear slider arm and the rear lock.Type: GrantFiled: November 27, 2018Date of Patent: December 28, 2021Inventor: Andrew Buerk

Patent number: 11198228Abstract: A knife includes a body, and a blade slider slidably mounted within the body, the blade slider configured to hold and slidably move a blade relative to the body. The knife further includes a blade snapper pivotally coupled to the body, positioned such that when the blade slider selectively positions the blade to be engaged by the blade snapper, pivotal movement of the blade snapper imparts a force on a blade segment of the blade to detach the blade segment from the blade.Type: GrantFiled: November 18, 2019Date of Patent: December 14, 2021Assignee: Stanley Black & Decker, Inc.Inventors: Eric Ranieri, Antony Orsini, Keith Lombardi

Patent number: 11179859Abstract: 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.Type: GrantFiled: March 7, 2014Date of Patent: November 23, 2021Assignee: PenBlade, Inc.Inventors: Branden D. Rosenhan, Benjamin Grover, Timothy R. Nieman, Andrew S. Hansen, Micah Frerck, Alex Drew

Patent number: 11141193Abstract: Embodiments of pelvic floor muscle incising tool of this disclosure include a housing that provides an effective way to shoe-horn the tool and its surgical cutting blade into a precise location between a baby's head and the mother's pelvic floor muscles. The housing provides a duckbill shape that allows for precise placement of the blade to create the incision, protects the baby from the cutting blade (creating only a posterior incision in the vaginal canal), distributes forces applied by and to the baby's head, and allows for concealed extraction of the blade after the incision has been made.Type: GrantFiled: October 30, 2018Date of Patent: October 12, 2021Inventors: William Clayton Martin, Corby Wade Smithton

Patent number: 11117273Abstract: A knife includes a handle body defining an interior blade-slide cavity housing a blade slide carrying a blade with a cutting edge. The blade slide is reciprocated within the blade-slide cavity between a blade-storage position in which the cutting edge is housed within the handle body and at least two blade-protruding positions in which the cutting edge protrudes to the exterior of the handle body, through a forward-end opening, to disparate extents. Blade-slide reciprocation is facilitated by a blade-slide actuator that includes a button reciprocable along an actuator slot defined through the handle body. A handle-body undulated surface defined along the handle body in the vicinity of the actuator slot is configured for selective mechanical interference with a button undulated surface in order to define the at least two blade-protruding positions. A blade-protruding position is temporarily maintained through a user's depression of the button to maintain the selective interference.Type: GrantFiled: November 20, 2019Date of Patent: September 14, 2021Assignee: HYDE TOOLS, Inc.Inventor: Romeo Arvinte

Patent number: 11104014Abstract: A tool includes a housing comprising first and second sides, and a slidable blade assembly configured to move between first, second, third positions. The blade assembly selectively receives a removable blade such that the blade is stored within the housing when the assembly is in the first position, a portion of the blade extends outwardly from the housing when the assembly is in the second position, and the blade is completely outside of the housing, and exposed for removal of the blade from the assembly without removing or separating any portion of the first side or the second side of the housing, when the assembly is in the third position. The tool further includes a first button associated with moving the slidable blade assembly between the first and second position, and a second button associated with moving the slidable blade assembly between the second and third position.Type: GrantFiled: August 15, 2019Date of Patent: August 31, 2021Assignee: Stanley Black & Decker, Inc.Inventor: Jimmy Gomez
