A cutting tool with handle and a cutting member that includes a feed slot with a cutting blade and a guiding member with a discus-like shape formed by two opposing convex surfaces is provided. The cutting blade is arranged on one convex surface leading the material to be cut into the slot to the cutting blade. The tool handle extends substantially parallel with the plane containing the at least one cutting blade in order to improve the manual control of the tool by pulling or pushing.

The present utility knife provides a uniquely improved safety mechanism that increases safety, reliability, and reduces the cost of manufacturing. A shield is locked over the blade by a strut braced between the shield and a stop within the housing. The strut is biased to the locked position by an integrally molded sinuous spring that is designed to force the strut into engagement with the stop and to force the shield to cover the blade, allowing just one cut per actuator pull. The stop structure checks the motion of the strut when locked and closely guides the movement of the strut when unlocked through use of an L-shaped channel. These features reduce the complexity of the safety knife and increase the reliability of the safety mechanism under rough conditions.

A multi-functional safe-touching tool allows a user to safely interact with door handles, touchscreen devices, or other objects. The multi-functional safe-touching tool includes a main shaft, a stylus, a door-handle claw, a bottle opener, and a user handle. The main shaft is an extension from a user's hand in order for the user to safely interact with objects. The stylus allows the multi-functional safe-touching tool to interact with a touchscreen interface. The door-handle claw allows the multi-functional safe-touching tool to engage a door handle in order to open the associated door. The bottle opener allows the multi-functional safe-touching tool to be used to open bottles. The user handle allows a user to efficiently grip the multi-functional safe-touching tool and provides leverage when opening doors using the multi-functional safe-touching tool.

A package opening knife has a body part, a blade part, a gripping part that extends in an elongated shape in a prescribed first direction, and a guide part provided with a guide surface that slides in a surface direction of the package in a state of contacting the package to guide movement of the blade part. When a surface direction of the guide is defined as a second direction, the first direction and the second direction become substantially parallel to each other.

A knife including a body with 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 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.

The present invention relates to a paper cutter, including a pipe body having a hollow channel, and a cutting tool mounted on the pipe body. The pipe body has a front end, a rear end, and a middle portion provided between the front end and the rear end. The middle portion is provided with a paper feeding gap and two guide inclined surfaces oppositely arranged. The arrangement that the paper feeding gap extends from the front end to the rear end through the guide inclined surfaces does not cause uneven cutting edges or tearing of a paper roll due to bending of edges of paper, such that a good cutting quality is achieved.
