In his book Bushcraft 101, Dave Canterbury recommends carrying two sizes of tarred twine in your back #12 and #36. He uses the #12 for making nets and fishing, and the #36 for heavy lashings or bindings and guy lines.

Tarred twine is resistant to oil, gasoline and other strength-reducing chemicals and abrasion.

Tarred twine is great for smaller survival kits, or Everyday Carry kits, since it packs down smaller than paracord does.
