Frequently Asked Questions (FAQ)

What is the best herb grinder to buy?

I am a huge fan of the new smart grinders. High-end ones are loaded with features including microchips and built-in scales that automatically measure the amount you’ve ground.

As far as ease and efficiency, however, these smart grinders really cannot be beat. They get the job done in seconds and make the task of grinding both efficient and fun.

They also handle multiple materials and can handle anything from tobacco and herbs to coffee beans and veggies.

I have had no issues with doing this and thus cannot suggest not to. However, it is common to find that you can grind too finely with these smart grinders, so it is fair to say that you should always display some caution when using these devices.

What is the best grinder on the market?

Without further ado, we give you the top herb grinder of all time: the Space Case Grinder. It’s made in the U.S.A. and it’s beautiful! It’s made with high-quality aluminum and comes in a ton of cool colors and different sizes. It’s also very affordable! The best part is, it really lasts. Some customers even report that they have owned a Space Case Grinder for 25+ years without any problems. This is the best grinder (period).

What is the best grinder for Kief?

Kief is the finest resin glands found on the cannabis plant. The glandular stalk that holds these tiny resin glands is called a trichome. Kief is more potent than hash and usually is preferred over hash when smoking because it provides a more immediate effect than hash.

Grinders are absolutely key in the world of cannabis. The herb grinder is kind of like a cheese grater on steroids. Herb grinders are best for grinding marijuana and especially kief.

What does grinder mean sexually?

Grinder is a term that refers to a person who frequents gay bathhouses. The origin comes from the late 1800s when bathhouses began installing circular wooden boxes with ridged sides on which to grind, or mix, their bath salts. They were informally called grinders from then on.

Nowadays grinders is a less common term for sexually promiscuous gay and bisexual men who have sex with other men while attending bathhouses and sex clubs.


If you’re looking for an herb grinder, you can’t do much better than the Space Case 4 Piece. They’re durable, nice looking, and will grind up your herbs to the consistency you want – chunky or fine. It’s hard to get a better option. Of course, if you’re looking for something to grind up weed only, then you can easily buy an herb grinder that’s just for that purpose.
