Spice Grinder For Aromatherapy

Personally, I stick with manual spice grinders that are hand held.  I use a basic two piece grinder by SharpStone to grind my spices.  It's high quality.  Made from hi-quality aluminum and CNC machined with razor sharp grinding teeth which shreds quickly and easily.  An intelligently placed o-ring reduces friction and wear.

It doesn't matter if you buy SharpStone or some other brand, as long as you ensure the product is food-safe.  Check out Kannastor, Chromium Crusher, Mendo Mulcher, and Space Case spice grinders.
