An optical source illuminates a portion of an animal nail, and an optical sensor receives light from the illuminated portion. A processor generates a signal level, and differentiates between a “quick” signal level range (arising from illuminated living tissue in the nail) and a “nail” signal level range (arising from illuminating a nail portion with no living tissue). An indicator informs a user when the signal level is in the quick or nail range, determining the location of living tissue within the nail. Source(s) and sensor(s) may be mounted on an animal nail clipper, with illumination by the source and collection of light for receiving by the sensor occurring at a position relative to a blade so that when the signal level is within the nail range and the clipper is actuated to cut the nail, cutting of the living-tissue-containing portion of the animal nail is avoided.

A hand tool for cutting wire and a method for manufacture. The hand tool comprises a first part having a first jaw, the first jaw having a first recess; a second part having a second jaw and a second insert retention portion; and a first cutting insert disposed in the first recess, the second part being pivotally attached to the first part so that the second insert retention portion covers and holds the first cutting insert in the first recess, so that when the parts are squeezed together the first cutting insert is forced toward the second jaw to cut a wire there between. Preferably the two parts are identical. The method comprises forming the first part and the second part; forming a first recess and a second retention portion respectively therein, placing a cutting insert in the first recess, and affixing both parts to a pivot.

A cutting tool provides a device for cutting a plate glass corner. The structure includes upper and lower blades which are opened and closed to cut the plate glass. The upper and lower blade edge lines mutually oppose each other to form a cutter body having a scissor shape. The upper and lower blade edge lines also coincide with the planned cut line of the corner section of the plate glass.

The present invention is to improve the mechanical characteristics of a pyrotechnical parachute line cutting device. By enforcing the mechanical traction on the electrical connection wire by Kevlar reinforcement cords. The flexible electrical wire will be connected straight to the propellant detonator to avoid wire connections and fix the detonator trigger straight on the flexible wire. The reefing line will be cut by the blade but also, to secure the cutting action, be melt in the head of the cutter blade after explosion due to the use of special knife material size and an adapted pyrotechnical charge.

A manicure implement is coated with a corrosion-resistant, wear-resistant material, such as zirconium nitride, titanium nitride, di-titanium nitride, and titanium carbonitride. Deposition is preferably accomplished by a cathodic arc process using linear deposition sources with simultaneous heating and rotation of a manicure implement substrate relative to the deposition sources.

A shear device includes a pair of handles having one end pivotally coupled together at a pivot shaft, and a pair of cutter blades secured to the handles and each having a notch. A knob is slidably engaged in the handles and includes a pin for engaging with the notches and for securing the cutter blades together. A button is slidably engaged in one of the handles. The knob includes a pawl for hooking to the button and for securing the knob to the button such that the knob may be secured to the handles and such that the pin may not be disengaged from the notches of the cutter blades.
