ROK
ROK builds hand-powered espresso gear that needs no electricity — you lift the lever arms to draw in hot water, then press down to generate the pressure for a real shot. It's a low-tech, travel-ready way to pull espresso with total manual control, paired with an all-metal hand grinder built to match.
