It is being sold as a necklace, but unless you are "Mr. T in the 80's" or a wanta-be-rapper nobody would wear anything this large and heavy. The review process asked me if this "toy" was fun, educational, and durable. I am not sure what this thing is, but it not a necklace and not a toy. It is however a pretty cool knife if you ca find a use for the rest of it LOL.
