A safety utility knife includes a pair of blades at one end of a handle. The cutting edges of both blades are configured to be shielded by a guard member. The guard member is movable with relation to the blade member.

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 utility knife (100) includes a body portion (120) including a sleeve portion (124) at a first end thereof and a heel portion (122) at a second end thereof, and a blade (110) that extends from the sleeve portion. The body portion includes a wheel assembly (140) including a wheel (142) rotatably disposed about a hub (146). The wheel is configured to support the utility knife during a cutting operation relative to a material being cut. The wheel is disposed on the hub to enable axial movement of the wheel to change an alignment of the wheel relative to the blade.

A fastener for fixing a pair of opposing flaps of a box in a closed state includes a receiving part extending along a first direction, with a flap abutting part configured to abut surfaces of the flaps being arranged on at least one side of the receiving part, the flap abutting part constituting a tab part for which at least a portion is curvable or bendable upward, a linking part having a rod shape and extending from a center portion of the receiving part, and a pressing part having a rod shaped that extends outwardly from an end of the linking part along the first direction, the pressing part being configured to be inserted into a gap at a juncture of the flaps so that spaces on both sides of the linking part between the receiving part and the pressing part constitute insertion areas into which the flaps are inserted.

A fastener is configured to fix a pair of opposing flaps of a box in a closed state. The fastener includes a receiving part, a pressing part opposing the receiving part, a linking part interposed between the receiving part and the pressing part, spaces on both sides of the linking part between the receiving part and the pressing part constituting insertion areas into which the flaps of the box are to be inserted, and a cutter part on the receiving part, the pressing part, or the linking part.

A knife including a body having a first end, a second end opposite the first end, and a longitudinal axis that extends centrally through the first end and the second end. The knife further includes a first scoring tip that points in a first direction, a second scoring tip that points in a second direction opposite the first direction, and a scoring tip axis that extends centrally through the first scoring tip and the second scoring tip. The scoring tip axis is perpendicular to the longitudinal axis. A chisel extends from the second end of the body and the longitudinal axis of the body extends centrally through the chisel.

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 safety utility knife includes a pair of blades at one end of a handle. The cutting edges of both blades are configured to be shielded by a guard member. The guard member is movable with relation to the blade member.
