Ceramic tile file
When glazed tile is cut it has a rough, ragged unfinished edge. You can dress that unfinished edge by smoothing it with a ceramic tile file. This type of file has carbide grit cemented to it, the same as is used to tumble stone. It's this strong abrasive grit that smooths the raw cut edges of porcelain, stoneware and earthenware ceramic tiles. A ceramic tile file is a handheld tool that anybody can use.
Cut a tile with a manual or electric tile cutter.

Set the tile on the edge of a work surface with the cut surface hanging over the edge. Press down on the back half of the tile with the heel of the non-dominant hand. Holding the tile file in the other hand, set the carbide edge against the rough edge of the tile. Set the file against the tile about one inch in from the tip and push down in a smooth, downward stroke.
Repeat Step 2 until the cut edge of the tile is smooth. Finish by rolling the file slightly over the edge on the downward stoke. This will give the tile a slightly rolled, beveled edge.
The raw edge of a cut tile is as sharp as glass, and can cut you.
