Is this it?
If so-the first one is wheeled nippers, for glass or china to cut small pieces. On a piece of glass, place the wheels in the center of the line you wish to cut and squeeze.
The second tool is a tile cutter, it has a small wheel. use the wheel to score a line on a plate,tile or shard, then flip them over and line up the score line in the center and squeeze-poof, broken plate or tile.
The third are tile nippers, use them to nibble off pieces of shards, or to cuta shard into smaller pieces. Place the jaws at the EDGE of the shard, about 1/4 inch in and squeeze. This might help you some....

Thanks alot, those are them. I'm not used to using tools for any mosaics, I use a hammer for tile and a glass cutter for glass. I'll go into my shop this weekend and try again. Will they work on glass?
Thanks again

Wheeled nippers work best on glass.

I think you will really like the tile cutter and nippers for your china. I actually cut a plate into strips with it and then use the nippers to cut the strips into tiles.
Here is tutorial on various ways to cut up a plate...everybody does it differently.
The wheeled nippers can help you shape glass with a lot of control and nip tiles as well.
