Why isnt your video first? I had to go thru a ton of fools to get here. This works, theirs dont!

Good video!

Great tip, man! What adhesive do i use to stick the tile trim unto the newly-filed flat tile though?

This works if the tile is the same color all the way through like this tile. But if the tile is a light colored glaze, with a terracotta color base, then rubbing the chip smooth exposes the dark color which can show through. Also some porcelain tiles are so hard, the sanding stone doesn't do anything to it. Just grinds a line in the stone.

Do you think this technique can be used after grouting which has highlighted the chipping.

What's the approx. granulation on this sharpener? Surely any product with the same grit can do the job?

Just Rubbing down with a wet diamond pad it will hide the chip round the edges with make look like chamfered edge 👍

Just get a variable speed grinder with diamond polishing pads. Works way better
