Manual coffee grinders, or hand grinders, can be an excellent way to achieve amazing grind quality while saving a bit of money compared to an equivalent electric model. While you might lose the convenience of an electric motor, you often gain superior build quality, a great set of burrs, and let's not forget you can work out your arms a bit every time you grind! Hand grinders aren't for everyone, but if you don't mind adding a little manual labor to your coffee brewing routine a hand grinder will be an extremely rewarding investment!
