Wait a second, those micro-chips end in the cut food pieces, right? How "micro" are those and how much of those are made on average in a cutting session? I am pretty sure that steel dust, starting from some size of specks and general amount of it, is not very healthy for internal consumption so I'd like to learn more.

On the contrary, dietary iron, the kind you need, is just iron. There's a fairly common science demonstration where you blend up fortified breakfast cereal (I saw it done with corn flakes) and pass a magnet over it. The magnet will pick up a bit of iron dust. The amount of steel flaking off a knife into any given meal is likely much smaller than how much iron is in the food on its own merits.

  There's also using cast iron to introduce iron into the diet. Food prepared in iron cooking pots as an intervention for reducing iron deficiency anaemia in developing countries: a systematic review - https://pubmed.ncbi.nlm.nih.gov/12859709/ https://pubmed.ncbi.nlm.nih.gov/12859709/ It's also something that many vegans have looked into https://plantprosperous.com/cast-iron-cooking-for-vegans/ https://plantprosperous.com/cast-iron-cooking-for-vegans/ (which links to the above article too - though I found the nih one first) My search-fu is failing me at the moment, but that was also believed that this was an important part of the pioneers heading west in the early parts of United States history.

      That's the first I've heard of it... so I looked it up. https://brightthemag.com/lucky-iron-fish-raise-questions-about-how-best-to-address-anemia-cambodia-d65bd66cf228 https://brightthemag.com/lucky-iron-fish-raise-questions-abo... and https://pubmed.ncbi.nlm.nih.gov/28049274/ https://pubmed.ncbi.nlm.nih.gov/28049274/

Those micro-chips exist on all knives through all kinds of cutting. VG10 just is designed for those chips to sustain the sharpness of the knife, so it requires less sharpening. You can look at the ends of any knife that's been worn away, and its not as smooth as when it was originally sharpened. The knife's edge is the thinnest part of steel, and may only be a few atoms thick when properly sharpened. It doesn't take much for it to chip off.
