What is the difference between Bill and Fracture?

The difference between bill and fracture is that “bill” is any of various bladed or pointed hand weapons, originally designating an Anglo-Saxon sword, and later a weapon of infantry, especially in the 14th and 15th centuries, commonly consisting of a broad, heavy, double-edged, hook-shaped blade, with a short pike at the back and another at the top, attached to the end of a long staff and “fracture” is an instance of breaking, a place where something has broken.
