Lucky cutlass

The lucky cutlass can be bought from Smith on Mos Le'Harmless for 2560 coins after completing the quest Cabin Fever. A book o' piracy is required to purchase it, and requires 30 Attack to wield.

It was previously owned by a pirate named Unlucky Jenkins, who died after a long series of improbable and very unlucky calamities. After his gruesome demise, his cutlass was discovered, untouched. The other pirates concluded that, having survived so much terrible bad luck already, it would be impossible for it to go through any more bad luck.
