New blade finish on Chinese knives?

[freewheeling]

Ran across this knife description on one of those Chinese sites:

Place of Origin: Guangdong China (Mainland)
Type: Folding Blade
Brand Name: other
Model Number: L2001
Surface: oxidation
Is_customized: Yes
Application: Hunting Knife
Type: Folding Blade Knife
Handle Material: alu
Blade Material: 5cr13

So apparently the new rage is custom knives with a rust blade finish? Makes sense.

Magnetite is a non-corrosive oxidation of iron.
