Frayed lines and ropes are easy to prevent with a simple whipping.
Whipping the line you use is a mark of someone who has pride in their work and tools.
This is a demonstration of what I was taught is called a temporary whipping. As opposed to a needle whipping which is more durable.
But this simple and easy whipping is usually all that is needed in most situations. And it’s certainly better than what most people do. Which is nothing.
