Cool Stuff for Mosaic Artists
Leponitt Wheeled Nippers
Leponitt is the brand of choice for many mosaic artists because they set the standard for quality and durability in nippers. They cut stained glass, smalti, vitreous tile, ceramic, china, and even agate. They include an Allen wrench so you can rotate the blade to keep a sharp cutting surface. See this How it Works video and the video "Cutting Complex Shapes".
