This is PAX's own grinder, with a square body that is easy to grip and a threadless design. The halves snap together with magnets, so there are no threads to cross-thread or clog with sticky material.

The grinder gives you the medium grind PAX recommends for the Flow's hybrid oven. Everything collects in one deep well. From there you can tip it straight into the Flow's loading funnel, or into the Puck Press for a compact, evenly packed puck.
