7 best glass cutters

Glass, unlike metals and wood, is very fragile, and therefore cannot be cut with abrasive tools. Glass cutters that scratch the top layer have been developed for cutting such materials. After that, by pushing it flat, you can gently break off the glass or mirror, exactly along the cutting line. This tool can be used to cut shapes with smooth edges as well as arbitrary shapes. We have compiled a rating of the best glass cutters, dividing the models by category. Experts have analyzed user reviews and product characteristics, so the review will help to navigate and buy the right model for the tasks ahead.

Best Diamond Glass Cutters

Diamond is one of the hardest materials on earth, which is why it is effectively used in glass cutters for straight and shaped glass and mirrors. The carbon piece is fixed in the holder with silver solder and stays fixed. With a diamond tool, you can drive a cutting line of up to 10 km with a thickness of the material to be cut up to 10 mm. So spend once and you will get a product that will last for years to come. But it is more expensive than other types. By the shape of sharpening two variants are applied: pyramidal and oblique. The first one is chosen by professionals, the second one suits beginners better. As the diamond wears away, it is straightened on a diamond sharpening wheel.
