Janus was the ancient Roman God of beginnings, transitions, doorways and time. He is generally depicted with two faces, one looking to the past and the other looking to the future, symbolising the constant movement between them.
The Janus razor looks at the Gillette Toggle and depending on your viewpoint, trys to or does improve it.

Its officially a Model 3000.
It was designed and built in Minnesota, US of A. Its manufactured in Stainless Steel. It was first announced in late December 2018. There wasn't much interest in an expensive Toggle homage and in May 2019 a Kickstarter campaign was started and ultimately failed. Eric, the designer announced that the initial run would be 51 (his 1 plus another 50) and managed to sell the 50 through word-of-mouth through various shaving forums.

It took a while, but I finally managed to get one of the Prototype models.
