Toothier With Time?

[Thirteenth Star]

Will corrosion on a blade from moisture such as that in air or perspiration cause an edge to become toothier? A knife of AUS-8 that I've never really used to do much cutting, but that I've carried somewhat often for two years, seems toothier now than I remember it once being.

Chipping damage can increase slicing aggression on a heavily worn edge, so yes it is possible.

It's not always a bad thing, toothy sharp sometimes cuts better.

Absolutely. I prefer toothy over smooth.
