My wife swears that steel particles are going everywhere and its making our the room a hazard for eating and breathing. I am confident that using W/D sandpaper for like a 10 minute session on a single razor indoors is totally safe as long as I wash my hands and wipe down the area I sanded. She does not believe me and is absolutely sure that what I am doing is very dangerous for our health. Whatever I say, she wont believe me. So I am asking in here because most of you are professionals about this. Is what I am doing dangerous? or are the dangers of using sandpaper on a single razor not that big of a deal indoors as long as I wash my hands and wipe off the area? And this is by hand btw, not a rotary tool or anything.
