Liquidraw Portland Navigation Divider Marine Nautical Single Handed Straight Divider Solid Brass 8"

Bought this instead of the Blundell divider that I had to return. Much better quality

I use these near weekly for nautical chartwork.I've used them for over a year and they have a perfect stiffness to them, they don't collapse on themselves but it isn't stiff enough to the point your forcing them. Great product, great price.

Easy to use and holds a distance well to enable accurate calculations.

Have had to return

Easy to use and very well put together

The hinge is appropriately sticky.
