GM laser protractor

Product detail

A laser protractor, also called a goniometer, is used to measure blade edge angles. It is especially important if you need to find out what angle your knife blade has before sharpening. In the same way, after grinding, you can check to how you control grinding on the grinding stones.

The GM goniometer has a continuously adjustable magnetic blade port. The angle scale can also be smoothly adjusted. Strong magnets allow accurate and comfortable measurement. To protect the blades, we recommend covering the magnets with thicker protective tape. The laser generator is powered by a built-in rechargeable battery. It is charged using a standard charger for mobile phones with a USB type C connector. The charger is not part of the package.
