That is the boiling point
The sharp part of a katana is located on the outer curve of the blade. This design allows for effective slicing and cutting motions when the sword is swung. The inner curve, on the other hand, is typically the flat side of the blade, which helps in guiding and stabilizing the cut.
Parts of a flat iron include the heating elements, which are internal, and the straightening plates, which actually straighten the hair. Another part is the clamp and body, the external parts.

whatis the flat part of the seafloor called?
It is part of a curve. If that curve happens to be a circle, then it is a fraction of a circumference but it need not be.

Without getting technical; The pressure differential is caused by the shape of the wing. The bottom is essentially flat while the upper part has a curve to it. As air passes over it, it must travel further past the curve but it still meets up with the air that went under the flat part of the wing at the same time. Since it covers a longer distance in the same time it has to move faster. That speed lowers the air pressure. If you want to see that in action, hold a piece of paper out flat and blow air above it, you will see it rise.

If the curve is part of the circumference of the circle, it is called an arc.
