Round Spinning Objects - Titanium yoyo with Brass rings!

It's been a long journey to complete the latest RSO model. Two years, seven prototypes, and four different machinists later and they have finally succeeded with a version that was worthy of a release! This is the DOOMBOT!

The DOOMBOT is a Titanium yoyo with Brass rings with a design inspired by high end Japanese models suited for fast speed combos and complex tech. It has a V-shaped catch zone that provides an aerodynamic advantage, helping the yo-yo cut through the air. The stepped profile also allows for a generous and more forgiving catch zone.

Most of us are familiar with the typical bimetal yoyo marketing spiel about their more peripheral weight distribution, higher moment of inertia, and longer spin times. All these hold true for the DOOMBOT, but there is much more. It has significant weight due to its wide dimension, coupled with the very high density of brass (even higher than that of stainless steel). And from a manufacturing standpoint, brass is a very difficult material to work with. Brass is a very soft metal (compared to stainless steel or titanium), increasing its risk of warping during the machining and press fitting process. Getting it just right is an accomplishment in itself!

Like all RSO releases attention to detail is second to none, giving the DOOMBOT a very special feel. It comes with a beautiful enamel pin, numbered certificate, and more all packed in a custom canister CNC machined out of red medical-grade Delrin. It also features custom samurai Gundam inspired artwork done by Firdaus (@freakyfir) from Studio Moonchild. A pioneer of the graffiti scene and one of the top graffiti artists in Singapore, he is a specialist in drawing robots.

NOTE: Due to the complex nature of it's construction, DOOMBOT A-grades have slight but insignificant vibe on grinds at the catch zone, but are generally smooth at the rim and on the string. B-grades (also termed Battle-grades) have additional vibe at the rim and on the string, and have more vibe at the catch zone.
