Shark's tooth necklace

The Shark's tooth necklace can be obtained after playing the Fishing Trawler minigame. It can be made by using 5 Shark teeth obtained from the minigame, with some thread. A Crafting level of 91 is required to make it, and doing so will give 170 experience. Crafting the necklace gives a message ''You string the teeth onto a necklace. It looks snazzy.''

Wearing the necklace will give the following effects:
 * The heal over time effect given when a baron shark is eaten is extended for an additional 5 seconds, giving it the potential to heal 2750 life points instead of the normal 2500.
 * A 5% additional Fishing experience boost is received when fishing sharks and baron sharks.
