What you should know about scissors

Terminology, materials, edge and blade

3. Machining of surface structure

Grinding scissors and shears is an elaborate manufacturing process that needs to be done with precision machinery. ZWILLING J.A. HENCKELS pays particular attention to the interaction of crescent, draw and twist. They are decisive in ensuring that the blades meet only at a single point along the lenght of the blades and that the material being cut is cleanly held and severed.

The manufacturing steps are:

grinding of the blanks: working of the edges and surface of the blank.
grinding the inner side and crescent.
grinding of the blades with inset and cutting edge.
shank and eye rings: the plastic handles (glass fibre reinforced polyamide) are injected on.

4. Assembly

During final assembly the shears blades are screwed together. The cutting performance and the easy closing action along the whole length of the blades are determined at this stage. Our fitters are highly skilled specialists.

The following steps are carried out during assembly:

assembly: the upper and lower shears blades are assembled with a bearing bush and screw and pointed, i.e. straightened.
marking: the trademark is etched in.
final inspection: testing the cutting capability and action of the scissors or shears and honing on an oilstone.

At ZWILLING J.A. HENCKELS particularly stringent quality control is carried out at all stages of the production process.
