Sengoku New Tri-Metal Model “Hideyoshi” will be released on Dec 11th.

The Hideyoshi will be released on Dec 11th. The idea behind the Hideyoshi, was what would happen if a second ring were to be added to create a tri-metal? The only way to find out was to make one and so it began. The idea was to distribute the weight in a manner that I couldn’t do with a single ring. The idea of lots of weight on the rims wasn’t an option, since placing 2 rings all the way on the edge made no sense, since it can be done by placing a single heavy ring.

While I was desingning the Nobunaga I noticed that there is a spot that affects stability. It can be noticed in Nobunaga´s inner cup, so I decided to place a brass ring there. I then added a larger stainless steel ring on the outer portion to give it power, I felt this was necessary given the low weight.

While no expert on metals or physics, I learned by experience that some times reality can be quite different than the results on paper, and even counterintuitive. I was still skeptical about a tri-metal until I got the first prototype, and in my opinion it feels different. Better, powerful, and stable. Having designed two full production products, and a slew of prototypes, I can say that I am VERY satisfied with the result.

Of course there was another probem, the cost. It would be a shame to release the first tri-metal ever and only making it available to a few collectors that can pay 300+ dollars. The design needs to be economically sustainable. A difficult decision was made to move production to China, some people will not like the idea, but I believe that many others will welcome a tri-metal for under $200 with the standard high quality product people have come to expect from Sengoku.

Based on the prototypes, majority of feedback I’ve received is positive and say it feels unique. It meets Sengoku´s high quality standards. A result I can stand behind.

The first run will be limited and sold at REWIND, YYE, La tienda del yoyo and Sengoku store on Dec 11th. $198 USD (3 units pre release available now!)
