Review on Navigational Divider Hand Stainless Steel by Tony Winn

This does the job I had planned. Maybe better? Naturally. The scale markings are probably intended for ocean mapping, not for making proportional drawings. The processing corresponds to my purposes. It came with someone else's scratches, but I didn't care. This is a tool that will eventually be covered in oil-painted fingerprints anyway. It is important for artists that a proportion, once given, remains the same, so there is no need to fear that it will slip into a different proportion. I'm only deducting one star because it's not exactly a drawing device.
