Cedar vs Willow: Which Bark Is More Flexible?

Measuring Bark Flexibility

When evaluating the flexibility of tree bark for cordage purposes, the most important factor is the thickness and fiber composition of the bark. Willow bark, in particular, is known for its relatively thin layers and high concentration of flexible fibers. To measure bark flexibility, you can try the “tear test”: strip a section of bark from a tree and slowly pull it apart to assess its tendency to tear or snap. For willow, the bark should exhibit a relatively high degree of flexibility, whereas cedar bark will be more prone to snapping.

Preparing Willow Bark for Cordage

Preparing willow bark for cordage involves stripping the bark from the tree in a way that minimizes damage to the underlying fibers. To do this, begin by cutting a section of willow branch at an angle, allowing you to peel the bark away from the wood. Start peeling at the base of the branch and work your way up, using a gentle pulling motion to remove the bark in long, thin strips. Once you have a sufficient supply of bark, you can begin to process it for use in cordage. This typically involves soaking the bark in water to rehydrate the fibers, then twisting or braiding the strips together to create a strong and flexible cord.

Harvesting and Working with Cedar Bark

While cedar bark is not ideal for cordage, it can still be useful for other applications, such as fire starting or water filtration. When harvesting cedar bark, be sure to choose branches that are relatively free of knots and other imperfections. To strip the bark, use a sharp knife or pruning saw to cut along the length of the branch, then gently pry the bark away from the wood using a flat tool or your fingers. Once you have a supply of cedar bark, you can use it to create a fireboard or other tool, or simply store it for future use as needed.
