TIMEMORE Chestnut X manual coffee grinder won Japan's Good Design Award 2020.Sturdy aluminum body with stainless steel burr,its max capacity is around 35g. Dual bearings central shaft ensure spinning smoothly with high centricity. Features Original secondary adjustment The 24-click point-to-point regulator allows you to adjust the grinding fineness directly.The precise secondary adjustment with 0.2 click operates like Swiss watches. It's a little tight at first using. S2C Burr 860 The patented and pioneering "Spike to Cut" burr is made of harder and durable SUS440 high-carbon stainless steel,hardness up to 58.5~60.5 HRC.Rust resistant and wear resistant.Spike coffee beans firstly and keep silver skin in large sheets.So you can have a cleaner taste.Fast cutting and less grinding also reduces fine powder effectively.Its performance is comparable to the firstline electric grinders. Aluminum Alloy Body The design of unibody is made of one-piece space aluminum alloy cut by CNC. Square to square thread alignment outside design allows you have a better hand grip experience. Convenient to Carry and Store The same as Nano's foldable sleeve structure,so the manual coffee grinder not only suit for home but also for traveling or camping.
