How to sand food safe glass by hand I have a few kitchen items that have become chipped from use (such as pint glasses and mixing bowls) and I would like to sand them to make the edges dull so they are safe to use again.

I saw the question that asked about sanding hand cut glass, but most of the answers talked about using electric tools and techniques. I would like to do it by hand because the pieces are not flat (oddly shaped), and not very large; a machine tool would be overkill.

What grit type of sand paper or other hand tools will help me with this task?

I know already I will need 


Proper eye wear 
Proper face mask
Some kind of lubricant
You would use a hand held diamond file.  They are sold specifically for the purpose you are describing (fixing chipped articles).  There are a number of articles and videos online which detail the process and specify which files to use (flat, rounded, etc.).
