A method for manufacturing a cutting tool having a rake face, a flank face, and an edge having a ridge line interconnecting the rake face and the flank face, wherein on the flank face there is a cutting edge region from the ridge line of the edge to a point A away therefrom on the side of the flank face by a distance X, the method comprising producing and processing the flank face with a laser, the producing and processing being producing and processing the cutting edge region along the ridge line of the edge with a first laser beam having a depth of focus equal to or deeper than a width of the cutting edge region when the distance X is the width of the cutting edge region, the distance X being 0.2 mm or more and 5 mm or less.

The present disclosure relates to safety blades for use in utility knives, related assemblies and methods of manufacturing. More specifically, the present disclosure relates to safety blades for use in utility knives, related assemblies and methods of manufacture which limit user exposure to associated cutting edges.

A method for manufacturing a cutting tool (10) with lubrication orifices of complex shapes, including the steps of: producing a polymer insert (20), overmoulding a body of the cutting tool (10) with the polymer insert (20) by injecting into a mould, removing the polymer insert (20), so as to form in the body of the cutting tool (10) lubrication orifices, the shape whereof is complementary with that of a part of the insert (20), machining the body of the cutting tool (10) on an active part thereof, and depositing an abrasive coating on a surface of the active part of the body of the cutting tool (10).

The shank (12) of a disposable rotary cutting tool (10) comprises a pipe section (16) cut from a drawn metal pipe. The tool head (14) is formed from a cut-out (18a, 18b) of a drawn metal sheet or a section of a metal tube by non-cutting machining. The pipe section (16) and the tool head (14) are advantageously attached by force fitting.

A mechanism, configured for positioning a work piece, includes a support member and a position assembly. The position assembly includes a guiding member and a positioning sleeve sleeved on the guiding member. The guiding member detachably is coupled to the support member. The positioning sleeve is detachably coupled to the support member. The guiding member is partially exposed from the positioning sleeve.

An ultrasonic surgical instrument comprises a cylindrical shaft and a blade at a distal or free end of the shaft, the blade being unitary and continuous with the shaft, without an intervening joint. The shaft has a longitudinal axis and the blade includes a flat or planar blade body with a proximal end eccentrically disposed relative to the shaft axis. Thus, the blade body or at least a proximal end portion thereof is disposed eccentrically relative to the shaft. The blade in its entirely may be inclined relative to the shaft axis or extend parallel thereto.
