You’ve seen the words, “Synthetic gut” used for a string. It’s a sexy term for something that is basically made of nylon. Nylon=plastic. Plastic ≠ gut. Gut is made of stretchy cow intestine. So is synthetic gut a synthetic “gut”? You be the judge.

But the string (whatever you want to call it) is still and good for control. Some are manufactured with additional materials which make them stiffer or softer. Some are much stiffer than natural gut. A really stiff string isn’t everyone’s cup of tea but it does offer some interesting hybrid possibilities.
