Knot Holding Capacity: Which Is Better, Paracord or Bankline?

Construction and Materials

Paracord 550 is made from a minimum of seven strands of nylon, with a diameter of 3.8mm, wrapped in a thick nylon outer sheath. Tarred bankline, on the other hand, consists of multiple strands of cotton or hemp, often wrapped in a tar-based coating for waterproofing. This construction difference affects their knot holding capacity and overall durability.

Strength and Weather Resistance

While paracord 550 has a minimum breaking strength of 550 pounds (249 kg), tarred bankline typically has a breaking strength ranging from 500 to 800 pounds (227 to 363 kg), depending on the specific type and quality. Paracord 550 also retains more of its strength in wet conditions, with a minimal loss of up to 10% in water, whereas tarred bankline can lose up to 30% of its strength when exposed to moisture.

Bushcraft Uses

In bushcraft applications, the choice between paracord 550 and tarred bankline ultimately depends on the specific task and environment. For general-purpose cordage, such as creating makeshift shelters, securing gear, or creating a makeshift tow line, paracord 550 is often the better choice due to its higher knot holding capacity and better durability in wet conditions. However, for projects that require a more rustic, natural appearance, such as creating a cordage-based fishing net or securing a makeshift bed, tarred bankline may be a better option due to its more aesthetic appeal and ability to blend in with natural surroundings.
