An agricultural cutting blade has top and bottom surfaces and mounting apertures extending through top and bottom surfaces. A cutting edge support surface (e.g. that may be a flat, pointed or rounded) is formed on the cutting blade body with the cutting edge support extending along a side of the cutting blade body transversely between the top and bottom surfaces. A clad material deposited upon the cutting edge support such as by laser cladding process. The clad material can be built up, that is layered in partial or full overlapping relation to provide at least 2 and often more than 4 layers of clad material at one or more locations. A cutting edge provided by the clad material that may be a ground surface into a laser clad bead.

A rotationally actuatable blade, particularly for automatic industrial slicing machines, the blade comprising a blade body which extends around a main axis and has a central region for fixing a spindle for actuating the blade with a rotary motion about the main axis and a perimetric region which ends toward the outside with a sharp edge, the transition region, comprised between the central region and the perimetric region, having a plurality of concentric circumferential bends which follow each other with alternating bending directions and with extensions, parallel to the main axis, which decrease from the central region in the direction of the perimetric region.

A tool including a tool surface and further including coding indicia linked, at least indirectly, with the surface of the tool, the coding indicia capable of being detected by a sensor, the coding indicia functioning as a pointer to information relating to said tool or its use.

A pencil sharpener assembly comprising a frame and a blade, the blade having an elongated sheet shape, one side of the blade being disposed with a blade edge, the frame being disposed with a pencil chamber, the blade being disposed along an axial direction of the pencil chamber and the blade edge of the blade being located in the pencil chamber, the blade being made of a ceramic material, the frame being disposed with a first positioning groove and a second positioning groove, the first positioning groove and the second positioning groove being oppositely disposed, a first end of the blade being inserted into the first positioning groove, and a second end of the blade being inserted into the second positioning groove. It has the advantages of being applicable to ceramic-made blades and the blade is not easy to fracture.

Various aspects of the present disclosure are directed toward blades having serrations, and methods for forming the serrations. As may be implemented in accordance with one or more embodiments, laser light is scanned across a surface of a knife blade in which the laser light is intersected with an edge thereof. The laser light is used to serrate the edge of the knife blade by generating heat in the knife blade while the laser light is scanned, melting portions of the knife blade at serration regions at the edge, and removing the melted portions. This approach may be carried out without registering an accurate location of the knife edge, and while also melting portions of the knife blade away from the edge.

A method for manufacturing a portion capsule which is filled with an extraction material for the creation of a brewed product. The portion capsule includes a main body of plastic, the main body having a base region, a peripheral side wall, and a peripheral main body collar that connects to the peripheral side wall. After the main body is filled, a plastic lid is placed such that a lid collar lies on the main body collar, and the lid collar is fastened to the main body collar. An outer portion of the capsule collar is then separated away with a separating tool having a blade. The blade has a first region of a first material as well as a second region of a second material, wherein the first region forms the cutting edge and wherein the first material is harder than the second material.

A tool including a tool surface and further including coding indicia linked, at least indirectly, with the surface of the tool, the coding indicia capable of being detected by a sensor, the coding indicia functioning as a pointer to information relating to said tool or its use.

A device for taking a sample from a solid body by cutting out, having a frame and a cutting tool retained on the frame in such a way that the cutting tool can be moved relative to the frame, wherein the cutting tool, at least in parts, at least substantially has the shape of a hollow spherical cap or a hollow spherical segment. A method for taking a sample from a solid body by cutting out is implemented with the device.

The ceramic sintered body of the present disclosure contains zirconia as a main component and includes sintered body crystals and a grain boundary part located among the sintered body crystals. One of the sintered body crystals contains cerium. A content of the cerium is less than 8.0% by mass. The grain boundary part contains silicon dioxide.

Produced is an iron-based sintered alloy in which hard particles derived from a titanium carbide powder are dispersed in the form of islands in a matrix comprising a two phase structure of austenite+martensite. The iron-based sintered alloy is obtained by mixing the titanium carbide powder, a Cr powder, a Mo powder, a Co powder, a Fe powder and a powder of Al, Ti or Nb so as to obtain a mixed powder that contains, in terms of mass %, 20-35% of titanium carbide, 3.0-12.0% of Cr, 3.0-8.0% of Mo, 8.0-23% of Ni, 0.6-4.5% of Co and 0.6-1.0% of Al, Ti or Nb, with the balance Fe, and then subjecting the mixed powder to cold isostatic compression molding, vacuum sintering and solution treatment.
