Utilizing "Cryogenic-Hardening" and Sub-Zero Processing for Extended Blade Sharpness within the Ophthalmic Knives Sector for 2026

A technical breakthrough gaining widespread traction in early 2026 is the use of "Cryogenic Hardening" for stainless steel ophthalmic knives. During manufacturing, the blades are plunged into liquid nitrogen at temperatures below -300°F. This process rearranges the molecular structure of the steel, turning "retained austenite" into harder "martensite." The result is a blade that is not only...
