Designed by James Osborne Spong, the Spong Coffee Mill is a hand-cranked contraption that Apartment Therapy claims makes a fine cup of coffee. While it still uses a blade instead of a burr, it’s unlikely that the speed of the grinder would build up enough to scorch the beans, one of the primary disadvantages of blade grinders. (How even the grind, however, is not mentioned.)
They’re no longer on sale, being upwards of one-hundred-years-old, but can be found on eBay here and there. There’s one listed now for $10, but it’s missing the nifty catch tin that doubles as a dust cap.
