Coffee Mill - Skerton Hand Grinder by Hario
This popular mill is perhaps the flagship of the Hario line. Hand crank ceramic burr grinding is adjustible from very coarse to very fine, and (importantly!) you can lock the adjustment in place so it doesn't tighten or loosen on you while you're grinding.
The bottom part where the grinds collect is glass, has enough capacity for a big pot of coffee, and comes with a separate lid so you can seal the grinds in the jar to keep them fresh. Also, the jar thread is the same as a standard mouth mason jar, so you can grind your coffee right into a mason jar!
