This is the "Solo Grinder," a hand-crank mill with stainless steel blades that grinds from extra-fine to coarse. It's brand new and unused. With this one grinder, you can enjoy hand drip coffee, French press, espresso, and more. Its light weight and compact size make it perfect for outdoor activities like camping and mountain climbing. The handle folds up, so it doesn't take up much space when stored. It comes with a convenient carrying case, making it ideal for those who enjoy the outdoors, don't want to accumulate a lot of gear, or want to savor the pleasure of hand grinding. It uses the S2C660 burr. The "S2C660 burr" is made of 420 stainless steel and is a high-hardness blade (equivalent to 55-58HRC) obtained through five-axis high-precision CNC machining. It shares the same concept as the S2C860 burr (Spike to Cut) used in the Timemore Chestnut X.
