Thief ones are around 1bil and Pirate ones go for cheaper, around 600-700mil

In BelloNova, it's quite uncommon to see them, maybe only 1 whipblade appears for about weeks... Clean Ravenhorn whipblades here are about ~2b while clean Sharktooth whipblades are 1- 1.5b here

They are kind of rare, so I can understand not seeing them, but they are around. I don't know about other servers, but the raven horn fallen queen is a lot more than the shark tooth fallen queen unless the buyer underprices it, so you're looking at 600-1.5b clean in broa depending on which whip and the price can actually go higher than that if the buyer is desperate. Saw a clean raven horn sold for 2b here once.

I have seen plenty in the FM, usually from cevmule1's store. I think he sells at 600-700M.

I believe they're 400m-1b depending on your server and class preference. I paid 700m for mine which isn't showing up for some reason >.<
