What are olive removers made of?
Content
Olive cutters
Olive cutters are usually made from hardened tool steels such as carbon steel and are often finished with a black oxide coating that gives the tool moderate corrosion resistance. The handles of some olive knives are covered with a plastic cap for a better grip.Carbon steel
Carbon steel is a steel alloy with a maximum carbon content of 2.0%. It is also used as a general term for non-stainless steel. Adding carbon to a steel alloy makes it incredibly strong, but it can also make the metal brittle.
Black oxide coating
Black oxide coating (also known as "blackening") is a thin layer applied to the surface of a material to enhance its resistive properties.
Olive Pullers
Some models of olive pullers are completely made of brass (with the exception of the T-handle). Other types are made from other tool steel alloys.
What are the advantages of brass?
The advantage of an all-brass tool, especially in plumbing applications where contact with water is likely, is that when the brass is fused to aluminum, a hard, thin, transparent alumina coating is formed that provides corrosion resistance. It also self-heals, reducing wear and tear.
What is meant by "self-healing"?
When brass is exposed to the elements, it tarnishes and its outer layers tarnish slightly. This tarnish acts as a protective layer that protects the metal from further corrosion. If the brass is scratched, it will "heal" with a new layer of tarnish.
