Fine Cutlery Forged from Minerals

ZIKICO specializes in products made of a unique material called zirconia, which is a type of ceramic made from minerals.


Zirconia has 3 main characteristics that give it the ideal properties for cutlery:


- It is derived from minerals that are nearly as hard as diamond and ruby.


- It is made up of two types of crystals, each with different properties that adapt to external forces.  This gives zirconia an even balance of metal-like hardness and suppleness.


- It is made by sintering at a high temperature of about 1400 degree Celsius (2550 degree Fahrenheit).  Much like pottery, zirconia does not release any metal ions or cause allergic reactions.



Hardness of gemstones


Suppleness of metal


Non-allergenic like porcelain



If one were to express all of these wonderful characteristics in one word, it would be "ideal".


ZIKICO is contributing to the universal dining experience by making full use of the wonders of zirconia.

Origins of the ZIKICO Brand


The brand name ZIKICO is a combination of  “Z” for zirconia, “JIKI” (the Japanese word for porcelain), and “CO” for corporation.


The logo is comprised of two overlapping rhombuses, illustrative of the crystal structures contained in zirconia.


High Quality Craftsmanship

Our unique powder injection molding and shaping process yield products with consistently beautiful lines.


All ZIKICO products are hand-crafted by expert artisans.
