Lifting scissors
.jpg){kind=small}
The scissors are a tool made of wood or metal used in glass processing and have the shape of tweezers with narrow, pointed sides but no cutting edges.
The lifting scissors are pressed together and brought into the opening of a glass body prepared for a vessel shape. As the two leaves gradually diverge, the opening is expanded evenly. The inner edges of the lifting scissors are used to create a constriction on the vessel held between them by the pressure against the soft glass mass.
A similar tool, which has cylindrical wooden sticks instead of iron leaves, is used to bend the walls of a vessel as desired.
