Quick Answer
Removing the inner bark is not always necessary for cordage. The outer bark, also known as phloem, is sufficient for most cordage needs and can be stripped more efficiently. The inner bark, or cambium, is better used for making rope when mixed with other plant fibers.
Why Strip the Outer Bark?
The outer bark is thicker, easier to strip, and more resistant to moisture, making it ideal for cordage. It contains a higher concentration of cellulose, a key component for rope strength. Most trees can be stripped of their outer bark without damaging the inner bark, which can be preserved for other uses. For example, the inner bark of certain trees can be used to make rope when mixed with 1 part inner bark to 5 parts other plant fibers.
Techniques for Stripping the Outer Bark
To strip the outer bark efficiently, use a sharp knife or a flexible branch to scrape off the bark in long, continuous strips. Start at the base of the tree and work your way up, using a gentle sawing motion to avoid tearing the bark. For smaller trees or branches, use your bare hands to peel off the bark. When stripping the bark, be sure to remove any dead or damaged areas to prevent weak spots in the cordage.
