Harley Benton Radius Gauge Notched 4-Set

The units and the radiuses are correct. The string spacing is fine too. However, only one side of the edges on each unit is treated/runded. The backside is actually rather sharp all around and might even leave scratch marks on the neck or possibly even hurting your hand if your unlucky.

If you’ve got a file or some sanding paper at hand it only takes a few minutes to knock those sharp edges off so it’s an easy fix.

You get what you pay for. These ones are really cheap, they are quite thin and you need to put in some manual work. I sort of expected this, which is why I set the overall grade as high as 3. Had they been more expensive, the grade would have been 1.

I don’t expect to use them for anything else than their purpose, so bending them when temporarily using them as a screwdriver or paint can opener or similar won’t be an issue for me.

After runding the edges they’re as good as any other brand out there when it comes to measuring the radius.
