What Customers Are Saying

The Kobalt glass cutter is a mixed performer. Many users found it effective for basic glass cutting tasks, praising its comfortable handle, smooth roller, and ability to make clean, precise cuts.

The cutter may not be suitable for more demanding applications or thicker glass.
