Hand-held cutting tool are provided that open blisters of a blister pill pack. The hand-held cutting tools includes a handle, an anvil, and a blade. The handle includes two arms having proximal and distal ends, and a connecting portion extending from the proximal ends of the arms. The connecting portion maintains spatial separation between the proximal ends of the arms. The anvil and blade extend from respective distal ends of the arms. The blade includes a cutting edge facing the anvil. The arms are configured to move between an open state and a closed state. When the arms are moved from the open state with the blister positioned between the anvil and the cutting edge to the closed state, the cutting edge is configured to puncture and cut the blister open to enable user access to pills inside the blister.

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 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 blade assembly, configured safely and efficiently pierce and shear an item. The blade assembly has a bottom member, configured to be joined to an underside of a glove finger with an adhesive. The bottom member further comprises a flat top portion. A block is joined the flat top portion and further comprising a raised portion. A blade is joined to the raised portion. A top member is joined to the bottom member and further comprising a flat portion with an opening. The opening surrounds the blade.

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 package opener includes a body having a first half and a second half. One or more blade cartridges are sandwiched between the first half and the second half, the blade cartridges including one or more blades, and for each of the one or more blades, a blade shroud which protects against accidental injury from the blade. The blade shrouds are constructed of a resilient material allowing the blade tip to cut into a material while the sides of the blade remain covered. The blade shroud can include substantially identical guard portions disposed along opposing lateral sides of the blades.

A box top opener employs a trapezoidal ceramic blade having a cutting edge which is positionable at multiple positions. A knob is rotatable to extend and retract the blade. A guide projects from a front of the cutter body to provide a guide surface engageable against the top of a box. In one embodiment, a blade carrier has a follower which traverses a spiral track for displacing the blade.

As shown in the figures, the device of the present invention is a hand held and hand operated cutting blade connectively attached to the bottom end of a pole that is housed in and partially contained within a capped cylindrical tube wherein there are tracks installed to guide the cutting blade up and down within the tube, and there are two openings (slots or channels) on the sidewall of the cylindrical tube which are used to be fitted over the sides of a box at the corner. As the tube is lowered to the bottom of the box, the blade will slide up into the tube and come to a rest positioned at the top of the corner of the box. The pole with blade can then be easily pushed down through the corner of the box cutting it from top to bottom.

The package opening device generally comprises a body portion, neck portion, and cutting member. In a preferred embodiment, the body portion comprises an elongated ovular configuration. The body portion comprises an upper surface and a lower surface. Adjacent to a distal end of the body portion is a through opening penetrating the upper and lower surfaces. Adjacent to a proximal end of the body portion, the upper surface comprises a recessed area. The neck portion extends from the proximal end of the body portion. Extending downward from a neck portion proximal end is the cutting member. The cutting member comprises a tapered tip.

Contemplated cutting systems are provided that include a blade, a blade holder, and a non-cutting surface. The non-cutting surface is configured to contact a surface to be cut. As the cutting system is moved across the surface and the non-cutting surface is rotated against the surface, the blade is configured to (i) pierce the surface with a first piercing edge and (ii) cut the surface with a first cutting edge. Contemplated cutting systems can be incorporated into hand or machine operated cutting tools.
