Measure Just Once.

Measuring has often been a tricky thing. Noah's cubit was the distance from a man's elbow to the tip of his middle finger.

The Roman Legions counted their paces.

Edward I took one step forward and called it the English yard. Then the pesky French came up with the metric system and confused everyone. Thankfully, we've settled all that.

Carpenter's Bone Ruler (No. 2590). Used before the ship ever left port, to ensure watertight compartments, bow angles and other important measurements. Again, in inches as well as centimeters. There's even a handy little three-inch ruler that slides out of an insert for measuring in tight corners. Imported.

Navigator's Bone Ruler (No. 2587). When man started circumnavigating the globe, things had to be a little more precise. If you were off by a fraction of an inch, you'd end up in Haiti instead of Cape Hatteras.To avoid such embarrassments, quartermasters would order precise bone rulers from instrument makers in London.

Ours is hand-crafted bleached bone, with brass accents. Includes both inches and centimeters. Imported.
