4. Space Case
Long time fan favorite, Space Case comes in 4th on our list. The cutting teeth are diamond shaped and extremely sharp. The grinder is made of titanium which means it is strong and can’t rust.
The Space Case also comes with a lifetime warranty, and it’s a durable product, to begin with. One downside is it has not been upgraded with rounded pollen trays yet. Another issue would be the hefty price on Space Cases despite there being more innovate grinders at lower prices.
