I distinctly remember the merchant in front of the Kelethin bank selling chipped bone rods during the Kunark era. It's weird that the only merchant on P99 selling it is in Thurgadin.
Anyway, I did a bit of research and found a post from allakhazam, dated Jan 22, 2001, confirming that merchant selling chipped bone rods. A followup post, from 4 days later, mentions merchants in S. Qeynos and Erudin also selling it.
