Since I got an Edge Pro sharpener, I have taken to examining my knife edges with a high-power loupe.
I see a few tiny nicks in the edge like this:
For these, I blamed ANOTHER PERSON who uses the kitchen, and probably, I guessed,
hacked frozen foods, or used the knives to cut wire.
But now I think the nicks are due to air pockets or small flaws in the steel.
For example, see below: the small hole in the steel will be a nick after the next sharpening.
The holes resemble pin-holes: one of the two holes below goes right through the blade.
These pictures are of a MAC MTH-80 that I've had a couple of years. I can see maybe 25 of these pin-prick holes in the blade. I can see similar (but fewer) holes in the blades of two japanese petty knives I have. I guess these 3 knives are VG10 or similar. My carbon Sabatier Trumpet has no such holes.
Are the holes manufacturing flaws which perhaps are inevitable with this type of steel.
Or is it a type of corrosion?
I like to wash and dry the knives soon after use.

Wow, never seen anything like that before!! Then again, I'm not using a high power Loupe, either. Interested to follow this one!
