Hario worked with Tetsu Kasuya to design the Matte Black Kasuya Drip Kettle Kasuya used a special technique in winning the World Brewers Cup Champion in 2016 so you know it's capable.

This kettle has an open top design to allow easy, quick filling from a traditional kettle so you can start brewing faster.
