The Great White Shark (also known as the GWS or Great White for short) by Spintastics is a yo-yo first released in 2000.
It was a variant of the TigerShark that has a beefcaked ball bearing setup that provides a wider string gap for advanced, low-responsive string tricks. Originally, the Great White Shark used starbursts, much like the TigerShark, while the later versions used friction sticker response.
