Is There a Difference Between Sinew and Tendon?

Anatomy and Preparation

To differentiate sinew and tendon, it’s essential to understand their composition and preparation. Tendon is a dense, fibrous tissue composed of collagen fibers, which provide strength and elasticity. Sinew, on the other hand, is made from the dried and processed tendons of animals, such as deer or buffalo. To prepare sinew, the tendons are typically dried and then pounded or scraped to remove excess tissue and fat. This process, called “de-fatting,” helps to make the sinew more pliable and easier to work with.

Cordage and Rope Making

When it comes to making cordage and ropes, sinew is often preferred over rawhide due to its greater flexibility and tensile strength. Sinew can be twisted and braided into a wide range of cordages, from thin twines to thick ropes. In contrast, rawhide is often too stiff and brittle for cordage making, although it can be used for other purposes such as leatherworking or crafting rawhide strips for lashings. To make sinew cordage, start by twisting two or three strands of sinew together, then braid or plait the twisted strands to create a rope. Experiment with different techniques and strand counts to achieve the desired strength and flexibility.

Practical Uses

Both sinew and tendon have a range of practical uses in wilderness survival and primitive skills. Sinew can be used as a cordage material, a binding agent for splints and casts, or even as a natural adhesive. Tendon, on the other hand, can be used as a source of protein in a survival situation, or as a component in making crude surgical sutures. In a pinch, tendon can also be used as a makeshift cordage material, although it may not be as durable or flexible as sinew.
