Stone River Sky

Sturm Panzer - Stone River Sky

Eclipse Ogre gets a bimetal variation!

A ferocious look belies how easy this yo-yo throws! Stone River Sky is the bimetal version of the Eclipse Ogre, the yo-yo at the heart of Sturm Panzer, tweaked and tuned to the max.

One strength of the Stone River Sky is the inclusion of the durable rim weight, which gives you the kind of power and spin you need to throw down some serious two-handed string tricks (3A) or counterweight long combos (5A). At 68 grams, Stone River Sky is a little on the heavy side for bimetal throws, and yet it is so nimble during play, you only feel the stability and not the weight during practice.

At the JOYC Final in the CW division, Sora Ishikawa used a Stone River Sky to take 1st place. A former member of Team YoYoJam, Ishikawa wanted to show respect to his former team, and so we're offering a special colorway based on his YoYoJam signature model, the "Next Level (Sora Ishikawa)." Incidentally, the character for "Sora" means "Sky."

This model is capable of installing 48mm side caps. To remove them, we recommend using a suction cup. If you are unable to remove the cap for any reason, you may need to drill a hole in it to make removal easier.

Set includes: Sturm Panzer Storybook 4-5 (A5, 50 pages, Japanese), the Stone River Sky yo-yo and a special edition accompanying postcard.

From the Maker
The bearing used is a size C concave/groove bearing, giving you great performance right out of the box. If you want even more, we recommend upgrading to an official Dif-e-Yo konkave bearing. Player assumes all responsibility for modifying their yo-yos.

We test every yo-yo to make sure that they are as stable as possible, and reject any yo-yos that fail to meet our standards. There may still be some vibes, but we have determined that they are within acceptable parameters.

Small cosmetic blemishes may be evident on the yo-yo, but are all results of the manufacturing process and have been tested to make sure they don't affect play.

from the Story
"The 21st century's new form of combat: Yo-Yo Fist. Since the Stealth Ogre incident in 2013, team Sturm Panzer was disqualified from the league, but has has been training and is back in combat. The date is 6/6/2015.

This time, they're up against last year's champions, Revol Bible. The first match will bring Gouki and the Eclipse Ogre to the arena. Kyoshiro and the Leo Sniper are up second, followed by Rayta and the Schneider. Gouki, who always leaves his opponents half dead, has no blind spots anyone can find, but his first opponent is the famous Shinya Kuragumo. Kuragumo's articles are what brought Rayta into the yo-yo world and inspired him to join Sturm Panzer... showing a deep connection between the opposing teams. But before the match, when Kuragumo offers a handshake, Gouki's face darkens. Will he be victorious, or will he fall to Kuragumo?

Next up is Kyoshiro versus Asuka Jio. Even before the opening games, The press corps was loudly proclaiming that the only one who could defeat the genius high schooler Asuka Jio was the other genius, Kyoshiro Aoi! Now it seems that this dream match has become a reality. Before such an opponent, Kyoshiro has found his fighting spirit waning, and has been training new strategies with Kasumi to improve his chances. But young Asuka seems to be only interested in his models... Everyone is excited for the conclusion of these matches!"
