Following again the fabrication of a sommelier knife, we can easily follow the manufacturing steps:

1. Cutting or die stamping of the metallic parts
   
   
   
   

2. Injection molds for plastic parts
   
   

3. Customization
   
   

4. Assembly (an important step)              
   
   

5. Finishes
    
   

6. Quality control and packaging
   
                              

There are five main marking methods:  Il existe cinq grandes méthodes de marquage :

1. Hot stamping for plastics (single color)
   
   
2. Pad printing for plastics (4 colors)
   
   
3. Laser engraving (all materials)
   
   
4. Chemical etching (metals only)
   
   
5. Embossing. Available for large quantities of metal parts. It allows a deep engraving that will not fade with time
   

There are several important criteria for selecting the best knife for the right use:

1. The blade needs to be micro serrated to easily and cleanly cut the capsule and remain sharp.
2. The number of spirals on the worm is not significant. It varies slightly with the models. The designers at SCIP match each size and pattern individually.
3. Single or double lever. The double lever is best adapted for ladies.
4. The material. It influences not only the price of the piece but also the weight of the knife.
5. Marking area. It must be balanced between the size of the knife and the size of the logo.
6. Color. It can be a matter of taste but must also respond to the exact specifications of the corporate client, using color charts.
