What are ceramic scissors made of?
These scissors are made of an advanced, high-tech ceramic called zirconium oxide (also called zirconia). This material, which is second in hardness only to diamond, was originally developed for industrial applications where metal components failed. Zirconium oxide is extremely hard, wear resistant, and chemically inert. For the technically minded, zirconium oxide has a hardness of 8.2 mohs (vs. steel at 5-6 mohs and diamond at 10 mohs).
