Cerakote - A form of ceramic paint, meant for coating the blade, that’s baked onto the surface of the steel. Like any paint, Cerakote doesn’t adhere well to an extremely polished or slick surface. The surface of the steel has to be roughed up through bead blasting or sandblasting to give the Cerakote something to bite onto and hold.
Parkerization - Parkerizing, or phosphate conversion coating, is a chemical treatment that protects a steel surface from corroding through oxidation. Parkerizing can only be performed on mild or carbon steel, so stainless, aluminum, and titanium blades are a no-go. Simply put, Parkerizing pre-rusts the blade before rust has a chance to take over. Rust happens, but with Parkerizing, we can beat it to the punch and guide the process on our terms.
