Whipping is a knot tied at the end of a rope to keep the end from unraveling. The benefit of the Common Whipping knot (displayed below) is that it is quite easy to tie and no tools are required. However, the knot is more appropriate for temporary use or on decorative ropes as it is known to slip off the rope easily. It is best used on a natural fiber rope and tied with natural twine, both of which afford the maximum friction for the knot to hold its position at the end of the rope. When dealing with synthetic ropes, it is best to wrap with tape and then heat the ends to melting point to fuse the strands.
