When chefs sharpen a knife before cutting into veggies and meat, shouldn’t we be concerned of eating microscopic metal shaving residue from the sharpening process?

Question

I always watch cooking shows where the chefs sharpen the knives and then immediately go to cutting the vegetables or meat without first rinsing/washing the knife. Wouldn’t microscopic metal shavings be everywhere and get on the food and eventually be eaten?

Answer 1

That is not, usually, the act of sharpening. It is a honing rod, to realign the wire-edge of the knife.
Honing rods come with a magnetic tip to catch those very shavings.
