The present invention generally relates to a safety cutter. Specifically, embodiments of the present invention relate to a compact safety cutter apparatus with a retractable blade guard. Embodiments of the safety cutter apparatus are further comprised of an automatic blade guard release mechanism.

The present disclosure relates to safety blades for use in utility knives, related assemblies and methods of manufacturing. More specifically, the present disclosure relates to safety blades for use in utility knives, related assemblies and methods of manufacture which limit user exposure to associated cutting edges.

A hand-held cutting tool includes a handle and one or more embedded blade cutters at a distal end portion of the handle, the cutter(s) each having a channel within which a blade with a cutting edge is secured/held, one of the channels including a protrusion shaped to laterally redirect an item to be cut in relation to a side wall of the channel and/or being provided in part by a wing portion of the cutting tool.

A safety blade for use with a knife assembly comprises a blade body, a bade attachment having a cutting edge and a top edge opposite the cutting edge, a blade attachment having a first half and a second half connected together via a hinge and extending beyond the top edge of the blade body to define a clamshell for receiving the blade body, and a handle adaptor having a handle engagement portion for removably securing the blade attachment to a handle.

A positioner for a carton sizer is provided. The positioner includes a housing and a latch. The housing houses the latch. The latch is pivotally connected to the housing. The latch may be pivoted between a latched position and an unlatched position. The positioner may be removably attached to a mast of a carton sizer at a selected height along the mast. The latch may engage the mast in the latch position to hold the positioner to the mast. The latch may disengage from the mast in the unlatched position. The carton sizer includes a handle and a cutter. The handle is connected to the mast. The positioner may engage a carton to provide support for the cutter against the carton during the cutting of the carton.

A package opening assembly comprising a package opening device and a securing housing, the package opening devise comprises a gripping portion and at least a cutting portion, and the package opening device is detachably integrated within the securing housing and wherein the securing housing is configured for attaching over a surface portion of a package.

A cutting cutter (10) includes: a blade piece (50) that is held on a blade piece holding part (30) so as to extend at least in a second direction (DB); and a guard part (70) that is movable, relative to the blade piece holding part (30), between a guard position in which a distal end of a blade edge (51) of the blade piece (50) is covered from one side in the second direction (DB), and an exposure position in which the distal end of the blade piece (50) is exposed to the one side in the second direction (DB); wherein when a first contact part (23) of a body part (20) is brought into contact with one surface (3) of a package (1), the guard part (70) is pushed by the one surface (3) from the guard position to the exposure position.

A food grade safety knife includes a safety knife blade, a handle, and a stepped region adjacent the juncture therebetween. The handle is defined by a pair of spaced apart major surfaces that include an enlarged palm portion; a flared end distal to the enlarged palm portion that anchors the safety knife blade, and a neck region intermediate between. The stepped region has a thickness greater than the enlarged palm portion. The stepped region rises in a plurality of discrete steps from the generally planar major surfaces and generally increases in thickness with increasing distance from the enlarged palm portion to a maximum thickness most nearly adjacent to the safety knife blade. At least one of the plurality of steps within the stepped region is provided with at least three generally linear segments each angularly offset from adjacent ones of the at least three generally linear segments.

A package opener comprises a handle having a first half and a second half. A plurality of blade cartridges are sandwiched between the first half and the second half, wherein the plurality of blade cartridges include at least one package opening blade cartridge, at least one dual blade cartridge, and at least one envelope cutting blade cartridge. The package opening blade cartridge is configured at an operative bottom end of the handle. The dual blade cartridge is configured at an operative rear end of the handle. The envelope cutting blade cartridge is configured at an operative front end of the handle.

A hand-held cutting tool includes a handle and one or more embedded blade cutters at a distal end portion of the handle, the cutter(s) each having a channel within which a blade with a cutting edge is secured/held, one of the channels including a protrusion shaped to laterally redirect an item to be cut in relation to a side wall of the channel and/or being provided in part by a wing portion of the cutting tool.
