How are Kyocera knives made?
First, we mold ceramic powder into blade “blanks” using special high pressure (many tons!) presses. Special binders in the powder allow the blanks to retain their shape before sintering (or firing), which takes several days at extremely high temperatures (in excess of 1000 C). We then grind (on a diamond wheel) and polish the sintered blanks to form an edge and the final shape before attaching the handle.
