A knife includes a blade, and also includes a first surface and a second surface extending at a predetermined angle toward a first direction, which is the cutting direction, and a third surface extending toward a second direction perpendicular to the first direction, wherein one end of the first surface and one end of the second surface form a vertex which is the blade while making contact with each other, and wherein one end and the other end of the third surface make contact with the other end of the first surface and the other end of the second surface, respectively.

A composition for coating confectionary and/or surfaces of food processing machines. The composition includes 60% to 99.09% by weight, based on a total amount of the composition, of an oil. The composition further includes 0.05% to 40% by weight, based on the total amount of the composition, of rice bran wax.

A rotary cutting implement and a lawnmower are provided. The rotary cutting implement includes an elongated body rotatable about an axis. The elongated body comprises a base metal and has at least one cutting edge. The cutting edge comprises an edge surface extending from a first surface of the elongated body to a second surface of the elongated body. The cutting edge further comprises a reinforcing layer adjacent to the second surface of the elongated body. The reinforcing layer is formed from a reinforcing composition comprising one or more reinforcement particles in an amount of 10 vol. % or more and a binder metal composition wherein a hardness differential between the one or more reinforcement particles and the base metal is 1600 HV or more. A lawnmower may include the aforementioned rotary cutting implement.

An apparatus for manufacturing a display device includes: a guide plate provided to contact a display panel; a cutting member which cuts a resin layer formed on the display panel along an edge of the display panel; a first tank which accommodates a cleaning solution for removing a residue of the resin layer adhered to the cutting member; a plasma treatment part which performs a plasma treatment on the cutting member; and a second tank which accommodates a hydrophobic coating solution for coating the cutting member with a hydrophobic material.

A needle array suitable for perforating a fibrous preform includes a backplate, a plurality of needles removably attached to and extending away from the backplate, and a collar disposed around each of the plurality of needles. Each of the plurality of needles includes a metallic body, and a polymer sheath covering the metallic body.

The blade comprises: a body portion; and an edge portion, the edge portion defining an edge of the blade and being secured adhesively to the body part. The body portion can be defined by a relatively low density material and the edge portion can be defined by a relatively high density material. The body portion and edge portion can each be defined by a respective metal, the metals of the body portion and edge portion being dissimilar. The adhesive can be a two-part methacrylate structural adhesive. The body portion can be 6061 aluminum and the edge portion can be 440C stainless.
