It takes roughly 60 Trades of any Abyssean (Kunai, Zahgnal, Spear, Shield) rusty weapon to reach the fame required to undertake the quest for the Scarlet Abyssite of Kismet, and these are the cheapest/fastest and most painless way to get it.
If you don't feel like burning gil, and have a Lv.30 Mule, get some Lugworms and a Composite rod, slap down 10 Rusty buckets in your home, and hit the lake near Baba Yaga. Plan on spending around 3 hours to get all you need for Rank 6 fame.
