Ryan La Grou showcases both of Sengoku’s latest models in his new video Senogku Team: Dream On. I’m a sucker for good yoyo videos with bamboo and waterfalls in the background. Makes it seem more majestic.
Sengoku is a new company based out of Nagoya, Japan whose focus is on producing premium competition yoyos. Following up on their first release, the Nobunaga, their sophomore release is called Masamune, and is named after a legendary swordsmith. Masamune, a bi metal created with stainless steel rings and a new material never before seen in the yoyo industry that is only available in Japan called Alumigo Hard. Here is what Sengoku owner Julio Robles has to say about the new alloy:
Alumigo Hard is an high tech alloy that is comparable to and even better than steel, relatively new, commercially available since around 2 years ago and made in Japan only.
In numbers, aluminum 7075 is far behind in all properties. Alumigo Hard also has excellent machinability and resistance to corrosion, and the most important feature is that unlike titanium Alumigo Hard is not extremely expensive.
This new alloy sounds absolutely amazing and the possibilities are endless. With all the talks about the new alloy, what about the yoyo itself? Well Sengoku has already prototyped and finalized the design of Masamune all while fully utilizing Alumigo Hard.
The walls are extremely thin and the Steel rings weighs more than 50% of the aluminum body weight. The rings were placed using nitrogen to shrink and make them able to withstand hits.
The Masamune will be available November 13th at select retailers, as well as direct through Sengoku.
