Straight-jawed tile nippers with tungsten carbide tips from FI Tools. Essential for any cut piece mosaic designs. Very good for cutting unglazed ceramic and marble (but consider wheeled nippers for cutting glass and smalti). Super-comfortable handles. To cut the tiles, hold the tile in one hand and the nippers in the other. Put the very edge of the tile between the jaws of the nippers, and then close the jaws applying gentle pressure.
