The Sushi Teaching Toy

Properly dissecting a fish like tuna may look easy when you watch the experts but it's actually much harder than it may first seem.
That's why Kazuyoshi Watanabe who runs a stand at the Tsukiji Fish Market in Japan has developed this toy to teach young children, and surely some adults, how  to properly dissect a tuna.
The toy comes with a chopping board, knife and ten separate parts that can be cut away from the fish.
It seems a great way to teach people how to properly understand the different parts of a fish but costing around $300 they don't come cheap.
