Bored with swords? Looking for a different kind of weapon for a martial artist in your fantasy novel?
Here’s a very interesting Quora answer involving a dart-tipped-rope weapon, with linked videos of the weapon being used.
This is called a rope dart, reasonably enough.
The problem with this would be that, if you put this kind of weapon in a novel, readers might not believe in it — an example of truth being less believable than fiction.
This kind of weapon might have several advantages. It should be relatively easy to get the materials and make one of these; it should be easy to carry it concealed. This kind of weapon would be unexpected. I imagine a rope dart would be difficult for an opponent armed with a sword to counter. A bow would beat this sort of weapon, though.
It does seem to me that a sling and a handful of good-sized pebbles would probably be easier to learn to use and would have a lot of the same advantages. But for martial arts coolness, a rope dart definitely beats a sling.
