never had anything that looked like corrosion.. not sure what kind of wood
would do that...

Pretty much anything green (i.e. wet), but particularly woods with high
acid
content such as cherry or oak.


It's the kind you _don't_ see. The fine edges that make the blade sharp are
the ones being pitted and eroded. If it gets so bad you see it on the sides
of the blade, you're sadly neglecting your cleaning. You can control some
of the corrosion by cleaning the teeth with WD40 between uses. Even if you
don't get all the acid-concealing cake off the teeth and gullets, you get a
bit of benefit in the WD -water displacement - category. Plus a smidgen of
lube for the next time you fire up.
