As of where it stands, it's not worth getting, because as an 800 gold 1 slot item that doesn't give much damage, and is based on kills is unreliable. Especially where Rengar stands currently.

Reasoning:[/Center]
Rengar is supposed to be a jungler, but as it stands, Bonetooth Necklace doesn't aid with his jungling at all. Having it build out of Hunter's machete, not only makes it a desired item to buy, but also increases the Jungle Utility whilst staying as a balanced item when facing other champions.
