The Rhino Coffee Gear Hand Grinder is a great solution for grinding coffee on the go; for travel, work, or even just at home.  With a smooth grinding motion, quality materials, and a convenient 42 gram capacity, the Rhino Hand Grinder is a perfect choice for manually grinding your favorite coffee beans.

A couple of helpful hints for adjusting the appropriate grind:

For grind to suit Aeropress, tighten nut all the way, then ease off half a turn
For French Press, ease off 1.5 turns
For a v60, tighten the burrs all the way, and then go half a turn back.  Some further adjustments may be required from there depending on the specific beans used. The suggested ratio is 60g/litre.
For a moka pot, which is somewhere between drip and espresso, adjust your grind to the finest level (adjust so that the burrs are touching) then open up a notch or two. It's best to pull the grinder apart and give it a clean every 4 weeks or more often if you are using darker more oily roasts.
Just use warm, soapy water and an old toothbrush to remove all residual coffee.
Make sure to rinse with fresh water when finished and allow the parts to fully dry before re-assembling
