A cutting implement including a metal substrate and a coating is provided. The coating has zirconium PVD (ZrCRTiNO), which provides protection against corrosion of the metal substrate. In some instances, the zirconium PVD provides protection from corrosion for at least 200 hours. A layer of titanium nitride (TiN) can be added to the coating to increase the hardness of the metal substrate. In such an embodiment, the layer of titanium nitride (TiN) is applied before the zirconium PVD (ZrCRTiNO). Titanium nitride (TiN) coated steel is 3 to 5 times harder than uncoated steel. Thus, a combination of titanium nitride (TiN) and zirconium PVD (ZrCRTiNO) as a coating on a metal substrate can increase the life of the metal substrate by providing increased hardness and anti-corrosive properties.

A cutting implement including a metal substrate, carbide edge(s), and coating is provided. The coating is zirconium PVD (ZrCRTiNO), which provides protection against corrosion of the metal substrate. In some instances, the zirconium PVD provides protection from corrosion for at least 200 hours. A layer of carbide can be added to one or more cutting edges of the metal substrate prior to the deposition of the coating. The carbide increases the sharpness of the cutting edges and therefore increases the life or longevity of the cutting edges. Thus, a combination of zirconium PVD (ZrCRTiNO) as a coating and carbide edges on a metal substrate can increase the life of the metal substrate by providing increased hardness, sharpness, and anti-corrosive properties.

An apparatus and method are provided for surgical removal of a ring. The apparatus includes guards rotatably connected, handles rotatably connected to the guards that each include a portion partially disposed within the respective guard, a guide connected to the guards, and blades disposed on the portion of the handles. The blades contact with at least one of the guide and an inner surface of the respective guard. A rotational axis of a joint between the guards, a rotational axis of a first handle and a first guard, and a rotational axis of a second handle and a second guard are substantially parallel. Movement of a first end of the first handle toward a first end of the second handle results in movement of a second end of the first handle toward a second end of the second handle, and movement of a first blade toward a second blade.

In opening and closing scissors, separation between both blades caused by inclination of one blade body relative to the other blade body is prevented or reduced. Specifically, with a head being in contact with a movable blade, a coil spring comes into contact with a head at one end and with the bottom of a counterbore at the other end. This pressing force allows a stationary blade to tightly abut on the movable blade. A taper face is formed at the stationary blade side of the head to press and expand the one end of the coil spring radially outside a pivot.

In one or more embodiments a system of foldable shears is provided, comprising a pair of shearing blades, each blade having a sharp side and a blunt side. The blades are connected to handles via a hinge, and the handles have one side that is straighter and another side that is more rounded or irregularly shaped. One of the blades includes a backward facing hook on the blade's blunt side. Additionally, the blunt side may have partially sharpened serrations or other features. The blades can fold about the hinge for easier transport and storage and the shears are configured so that the hook does not extend past the handles when folded to prevent catching the hook on anything or damaging any nearby equipment.

A cutting tool is provided which may include a first blade and a second blade, where the first blade is coupled to the second blade at a first pivot point, where the first blade defines a cam follower and pivots relative to the second blade about a first pivot axis through the first pivot point; and a lever pivotably coupled to the second blade at a second pivot point, where the lever defines a cam surface and pivots relative to the second blade about a second pivot axis through the second pivot point, where the second blade is driven toward the first blade in response to the lever being advanced toward the first pivot point and the cam follower translating along the cam surface.
