glass knife
Transparent cutting tool
A glass knife is a blade made from fractured glass, valued for its extremely sharp edge.
In laboratory settings, glass knives cut ultrathin sections of tissue for microscopy.
Obsidian knives—natural volcanic glass—were used by ancient peoples and are still prized by some surgeons for their superior sharpness over steel scalpels.
