The Shingen, named after the Samurai leader Takeda Shingen, is the first yoyo made out of 7175 alloy, a mixture of magnesium, zinc, copper and aluminum.

The yoyo industry standard is 6061 aluminum. A less common, and more premium option 7075, which has superior strength to weight, can be machined thinner, and is even a little harder to ding.

The 7175 alloy is a step above this. Its strength and rigidity are both superior, once again allowing for more extreme weight distributions. The Shingen makes full use of these properties to maximize rim weight. Add an extra large stainless steel set of rims, and you’ve got some serious angular momentum!
