Prima Coffee — with over 43K views — compares three Kinu models: M47 Classic (the original), M47 Traveler (compact travel version, now discontinued), and M47 Phoenix (the lightweight). This video offers a historical perspective on the M47 line's evolution.
All share the same 47mm burrs and proprietary Morse cone system — capable of grinding from Turkish ultra-fine to cold brew coarse. Key differences: Classic = full steel, heaviest, most solid. Traveler = more compact, lower capacity. Phoenix = lightest, most modern design.
Steve from Prima emphasizes: Kinu is the only brand in the premium hand grinder segment using the Morse cone — technology borrowed from precision machining. This completely eliminates burr wobble, producing significantly more uniform grounds compared to conventional bearing systems.
