A method for manufacturing blade beds of a garden shear, wherein each of two blade beds has a length and a thickness far less than the length; the method includes: using extrusion method to extrude two blanks in directions parallel to directions of thickness of two blade beds respectively, wherein cross sections of the two blanks are shaped into the two blade beds; slicing the two blanks perpendicularly to the extruding direction into a plurality of pieces at intervals of distances equal to the thickness of the two blade beds respectively; and chamfering a plurality of peripheries of the pieces by punching.

A method for making a bent razor blade is disclosed. The method includes: providing an elongated strip of stainless steel that can be 0.076 mm thick; hardening the strip; providing a cutting edge along an edge of the strip and providing coating(s) on the cutting edge. The stainless steel has a carbon content less than 0.60% and preferably between 0.45% and 0.55% by weight. The strip is separated lengthwise into discrete razor blades. The bent portion of the razor blade is then formed using a swivel bending process.

A shaving head that doubles as breaking mechanism to break a safety razor blade into two pieces to form a 2-blade shaving razor. The shaving head includes a front component having a retention guide, a first position stop and a second position stop at a distance offset from the first position stop. The shaving head further includes a back component having a blade slot configured to receive a first blade portion and a second blade portion formed from breaking a double-edge safety razor blade such that the first blade portion has a different width compared to the second blade portion. The retention guide is configured to retain the first blade portion and the second blade portion in the blade slot responsive to the retention guide being at least partially inserted into the blade slot. The sharp shaving edges once installed form a shaving angle between 5 and 30 degrees, where the shaving angle is determined by where the blade is broken.

A method for manufacturing blade beds of a garden shear, wherein each of two blade beds has a length and a thickness far less than the length; the method includes: using extrusion method to extrude two blanks in directions parallel to directions of thickness of two blade beds respectively, wherein cross sections of the two blanks are shaped into the two blade beds; slicing the two blanks perpendicularly to the extruding direction into a plurality of pieces at intervals of distances equal to the thickness of the two blade beds respectively; and chamfering a plurality of peripheries of the pieces by punching.

A method of manufacturing a component from a high-strength blank metal strip or sheet (MS) having a tensile strength of at least 850 MPa. The method comprises reducing the thickness (T) of the strip or sheet (MS) in a folding section (FS) so that a shaped section (SS) having a predetermined shape is obtained in at least a part of the folding section (FS). The strip or sheet (MS) is then folded along the shaped section (SS), so that a surface of a first section (1S) becomes arranged adjacent and parallel to a surface a the second section (2S) of the metal strip (MS). Finally, the first and second sections (1S,2S) are joined, so that the strip or sheet (MS) remains folded. With this method, it is possible to use high-strength steel, e.g. AISI 301 stainless steel, and still fold a thin strip or sheet (MS) without undesired cracks in the folding section. For example, the invention is applicable for manufacturing of plate-shaped hair-pulling elements (HPE) for a cutting unit (CU) of a shaving apparatus.

The present invention provides a blade cutting device capable of simplifying the work of cutting blade-shaped materials (31), and accurately forming blades. The blade cutting device includes a material accommodation section (32) comprising a plurality of accommodation chambers (R1 to R10) for accommodating the band-shaped materials (31) used to form blades, in such a manner as to be sorted by type; a band-shaped material machining section (33) comprising a feed unit for feeding a band-shaped material (31) pulled out from a predetermined accommodation chamber and a cutting unit (55) for cutting the band-shaped material (31) into a predetermined length for forming blades; and a control section for causing the material accommodation section (32) to move so as to locate the predetermined accommodation chamber of the material accommodation section (32) at a position facing the band-shaped material machining section (33). The predetermined accommodation chamber is located at the position facing the band-shaped material machining section (33), and the band-shaped material (31) pulled out from the predetermined accommodation chamber is cut into a predetermined length for forming blades. The work of selecting the band-shaped materials (31) can be simplified, and blades can be formed accurately.
