With a very sharp knife onions can sliced and cross sliced paper thin.
For very finely minced onion I prefer to use a grater, it's faster...
new graters should be sharpened, use a jeweler's file to remove the
stamping burrs from each piercing, doesn't take long and makes a huge
difference. Fumes can be dispersed with a fan or bring the project
outdoors and stand up wind.
