The process of making a Kikusumi ceramic knife involves 9 key stages before the finished knife emerges complete. Along the way there are multiple quality inspections made to ensure each knife meets the high standards we expect.
- Dry Pressing
- Cold Isostatic Pressing
- High Temperature Sintering
- Low Temperature Sintering for Kikusumi Logo
- Handle Injection
- Blade Grinding
- Blade Sharpening
- Blade Polishing
- Cleaning

CERAMIC KNIFE PROCESS
1. DRY PRESSING
2. COLD ISOSTATIC PRESSING
3. HIGH TEMPERATURE SINTERING
4. LOW TEMPERATURE SINTERING
5. HANDLE INJECTION
Kikusumi knife handles are attached to each ceramic blade by using and advanced injection molding process which is both stronger and more sanitary than using the glue and thermal bonding that many manufacturers use. The result is a knife with a stronger structure and superior hygienic properties.
6. BLADE GRINDING
7. BLADE SHARPENING
8. BLADE POLISHING
- Coarse Flat Grinding consists of polishing both sides of each ceramic blade with a diamond-dust This is a relatively fast and time-efficient process.
- Precision Flat Grinding the edges of the blades comes after the coarse grinding is finished. This is a slow and time-consuming process that results in a high-gloss surface on each ceramic blade.
- Open Edge Polishing produces the final refinement to the blade’s edge that is complete when the ideal sharpness is achieved.
