The Duhuk Lumia Matcha V4 linear switch is probably one of the most unique switches I have personally tried (this is very subjective). The TC308 stem is very special as it is extremely smooth even when there is no lubrication at all. If you hold the stem with two fingers, you can feel it slowly gliding down. Yes, that is how smooth it is. Another feature that comes with the TC308 stem is that it leans toward the softer side. That results in a very deep and thocky bottom-out sound, but the bottom-out feel is also a bit soft at the same time. When paired with the full LY housing, you can easily imagine how smooth and deep-sounding these switches are going to be.
One disclaimer about the Matcha V4 switches: There are rumors saying Grain Gold is the manufacturer. In fact, Lumia designed the molds and customized them with Grain Gold. Manufacturing is completed at Lumia's own facility, and the machines and materials used for production were all acquired by Lumia itself.
