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. However, some reported issues with thicker glass, insufficient scoring, and undesirable glass breakage. Proper use and maintenance, such as oiling the cutter, appears important for optimal results. The cutter may not be suitable for more demanding applications or thicker glass.

Works great

Would Recommend

The item was easy to hold and apply pressure on the glass. Rolling worked well. Using keoscene as a lubricant while scoring the glass. Made cuts crisp and needing little clean up work. Highly recommend.

Scribes very well.

Would Recommend

Good design for applying high pressure to the scribe. It might be better if it had a metal ball on one end for breaking the glass along the scribed line. This did not work well on 1/4" heavy glass and I ended having to break the entire window into small pieces with multiple, terrible shards. However, it must be said that I am an amateur with glass panes.

💩

Would Not Recommend

Buy something else. This is practically useless and the “blade” is so dull that I thought I was going to break the glass from the pressure I had to apply to get a cut
