As others have noted the surface of this compass/divider is a little rough - the slot in the wing needs a bit of sharpening and the tips need a bit of sharpening. I plan to use it as a compass so I ground the moving point. Ideally, the pencil stand should be at a slight angle - the smallest possible compass radius is about 1/2 inch. With a little modification, this is a reliable and accurate tool.
