The controller, developed by the National University of Singapore (NUS), transforms from a wobbly fishing rod to a rigid blade by flipping a switch. It was exhibited at the Tokyo Game Show 2015.

Reel Blade was created to test the Ninja Track. It’s about catching and then slicing up an octopus. It’s a little like Reel Fishing meets Fruit Ninja only with the one octopus—it is a hardware demo, after all.

Programmer Wei Kiat Leong addressed Reel Blade’s simplicity:

The Ninja Track, too, is still in development. Though NUS used 3D printing to create a prototype, the final version will be a more durable product. 3D printing is known for making fragile, breakable products. But even so, its prospects for game innovation seem endless.
