In today’s Knot of the Week series I’ll be demonstrating how to prevent natural fiber rope from unravelling after it’s cut. With repeated use, natural fiber rope like the sisal rope shown in this demonstration, can become loose and lose its twist. Whipping a rope can stop unravelling and untwisting for good.

With synthetic ropes like paracord or climbing rope, fraying at its end is easy to fix by fusing it with a lighter. With natural fiber, it doesn’t fuse or melt, so whipping is mandatory. I like using waxed dental floss for this, because it’s cheap and the wax from the dental floss helps the wraps of floss to adhere together, further protecting the whipping.

You can also go a step further and tape over the floss whipping to protect it even more. If you have precut lengths of natural fiber rope, say for scouting pioneer projects, colored electrical tape is great for color coding sets of different lengths of rope. Check out the video below to learn how to whip a rope!

(Strength: 3/Secure: 3/Stability: 3/Difficulty: 2See below for what these ratings mean.

Ratings

Strength/Security/Stability/Difficulty

Each knot will be assigned a rating from 1-5 (1 representing the lowest score) based on the following four properties:

Strength – All knots will weaken the strength of  a rope, however, there are knots that are stronger than others. The scale here will reflect how strong the rope remains with the specified knot.

Security – The security scale refers to how well the knot will stay tied, and resist coming loose under a normal load.

Stability – Stability refers to how easily the knot will come untied under an abnormal load (i.e. the knot being pulled in a direction it was not intended to) A lower score here represents instability.

Difficulty – The lower the number, the easier a knot is to tie.

    As a Boy Scout leader, we whip a lot of rope.  A good rule is to make the whipping two ‘diameters’ long, and stop the whip one ‘rope diameter’ from the end.  If you get too close to the end of the rope, the whipping can come off.  For example, on 1/4 inch rope, make your whip 1/2 inch long and leave 1/4 inch showing at the end.
