Chine

A chine of meat or fish is a cut which includes at least part of the backbone.

A chine is also a steep-sided river valley where the river flows through coastal cliffs to the sea. Typically these are soft eroding cliffs.

It can also mean the top of a ridge; the spine of an animal; a sharp angle in the cross section of the hull of a boat.

Chine is also French for China so when I googled for an image of a chine all I got were French maps of the far east!
