Darts as a weapon

Here's a quote I wish I had handy when I was writing one of my books:

"He discarded the darts, needle-sharp iron bolts eight inches long with a leather tail [. . . ]" - Jack Vance, Planet of Adventure, pg. 474.

The Khors and their throwing darts must have been inspiration for D&D's darts at some level. They are oddly omitted from the weapon list of GURPS Planet of Adventure, but stats for a throwing knife or paku would do well enough.
