is rust on knives dangerous

Is rust on Knives dangerous? Well, this seems like a big question for today. Rust is also called iron oxide.

A red and orange flaky substance that you see growing on metal. Iron oxide is from the reaction between oxygen and Iron, with water.

Is a rusty knife dangerous? Yes, chances are high that coming into contact with a rusty object, especially if it inflicts a wound could cause tetanus and other health issues. The tetanus bacteria takes advantage of rust to thrive.

Steel Types and how They Rust

steel types

Steel is classified into two types: stainless steel and carbon steel.

Carbon steel

Carbon steel is composed of iron, chromium, carbon, and other metals.

Chromium surrounds iron and protects it from oxidation by oxygen.

However, chromium reduces the durability of the blade. Sharpening is required more frequently than with stainless steel.

Stainless steel

Stainless steel is less likely to rust than carbon steel, but that doesn’t mean it won’t rust.

It can still rust due to heavy abuse. Titanium and ceramics do not use iron, so they are 100% rustproof.
