What is the method used to prevent a rope from unraveling?

Whipping is a technique used to prevent the ends of a rope from unraveling. This method involves wrapping a thin strand of twine tightly around the rope's end, which not only keeps the fibers together but also provides additional strength and durability at the end of the rope. The whipping should be done in a specific manner, often with several turns that can be secured, to effectively hold the strands in place and protect the rope from fraying or unraveling during use.

In contrast, fraying refers to the natural process of the rope's fibers coming loose, which is the opposite of what whipping aims to achieve. Twisting involves actually rotating the rope to create a tighter structure but does not address the unraveling directly. Binding is a method to secure multiple items together but may not effectively prevent the unraveling of a single rope end. Thus, whipping is the appropriate choice for this purpose.
