A bag cutter for opening a sealed package using at least one of a blade and a piercer. Preferably, at least one blade is disposed partially within a cutout of an arm in a manner that exposes an edge of the blade. A piercer can comprise an extension of a cutout edge or be located on any other suitable portion of an arm. Another blade can be provided that is substantially perpendicular to the blade within a cutout, and juxtaposable against a cutting surface.

A safety cutter adapted to open a box or similar packaging comprises a molded elongated handle which integrally connects with a protective head that mounts a fixed blade. The head extends transversely and has a protective canopy. Exposed portions of the blade, which is preferably ceramic, are protectively disposed at opposed portions of an upper end of the handle below said head. The handle has measurement scales and a contoured thumb grip.

A cutting device, including: a handle rotatable about a central axis; and at least one blade attached to the handle, a cutting edge of the at least one blade is at a first distance from the central axis; wherein the handle comprises an opening around the central axis configured to accommodate a protruded part on a surface to be cut. A method of using the cutting device is also disclosed.

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 knife has a body forming a cavity, a blade with a cutting edge, and a holder forming a tool seat and movable relative to the knife body between an operating position with the tool seat in the cavity and a change position with the tool seat outside the cavity. An additional tool has at least two working parts and is provided with a holding part that can be fitted to the tool seat such that, in the operating position of the holder, one of the working parts is in a working position in which it projects from the body and can be used by a user while the other working part is in a stowed position inaccessible in the cavity and, in the change position, the tool is entirely outside the body and can be separated from the seat.

A safety blade for use with a knife assembly having a handle with a cutting head engagement portion, the safety bade comprising (a) a blade body, a bade attachment having a first inner edge and a second inner edge, a first blade shield, a second blade shield, a first blade cutting edge, and a second blade cutting edge, and (b) a handle adaptor having a body portion and a handle engagement portion with a handle securing mechanism. The first blade cutting edge is positioned between the first blade shield and the first inner edge, and the second blade cutting edge is positioned between the second blade shield and the second inner edge.

A knife includes a handle portion and a cutting head portion. The cutting head portion includes a lid portion and a base portion configured to receive a blade therebetween. The lid portion is coupled to the base portion by a hinge. Rotation of the lid portion relative to the base portion away from the base portion opens a space above the base portion through which the blade may lifted. A method of removing a blade from a knife includes rotating a lid portion relative to a base portion about a hinge coupling the lid portion to the base portion, further rotating the lid portion until a protrusion fixed to the lid portion extends through the base portion and lifts up on the blade to create a gap between the blade and the base portion, and grasping the blade at the gap to pull the blade away from the base portion.

A glove comprises a flexible area configured to be worn on a hand of a user, the flexible area being positioned to be secured on a palm of the hand. The glove also comprises a reinforced area coupled to the flexible area, the reinforced area configured to engage a thumb of the hand and extend towards the palm of the hand. The glove further comprises a protrusion on the reinforced area, the protrusion comprising a blade. The protrusion orients the blade at an angle with respect to the reinforced area.

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.

A cutter includes a grip, a sheath, a blade and a magnetic unit. The grip includes two edges. The sheath is transversely formed at and end of the grip. The sheath and the grip are made in one piece. The sheath includes two openings made in a rear edge thereof, on two opposite sides of the grip. The blade is formed with a cutting edge. The blade is substantially inserted in the sheath, with two sections of the cutting edge exposed to the exterior of the sheath through the openings. The magnetic unit is attached to a face of the cutter.
