These are the Bohle/Silberschnitt Zag Zag Glass Nibbling Pliers - Model BO-701.0.
The professional nippers for the most demanding art glass requirements. Solid aluminum. The highest quality, best performing pliers available - anywhere.
German made, with carbide cutting wheels for long life, these pliers allow you to nip up glass, tiles, shells, pottery, etc. into small pieces for use in mosaic or stained glass projects.
The lightweight aluminum spring-loaded handles allow easy use with reduced fatigue and wrist/hand strain. Also includes a removable splinter bag designed to catch the pieces of glass/tile as they're nipped off (instead of shooting across the room). Designed for discriminating glass and mosaic artists, and for those who appreciate using the best quality tools available.
