Maintaining a consistent sharpening angle is crucial when using a guided knife sharpener. The angle should remain unchanged even when switching from one sharpening stone to another. To achieve this, it is important to measure the angle between the knife plane and the sharpening stone accurately.

Fortunately, there are a variety of digital angle gauges available on the market that can help with this task. One of the standout models is incredibly lightweight, which makes it an excellent companion to a knife sharpener.

Weighing just 3 ounces (85 grams) with batteries included, this gauge is powered by two AAA batteries (not included) and features a fast battery change system that doesn't require any screws. It also has two magnets on the bottom side to help it stay securely in place during use, and an LCD backlight that makes it easy to read in any lighting conditions.

With a measuring accuracy of 0.2 degrees and a resolution of 0.1 degree, this gauge provides precise and reliable readings. Its compact dimensions of 57 x 54 x 25 mm make it easy to store when not in use, and it is a valuable tool for anyone who takes their knife sharpening seriously.
