If you smoke dry herb you definitely need a good grinder. There are some cheap grinders out there you can get for only a couple dollars but we advise against it. If you are going to be spending your hard earned money on herbs you can probably invest just a little bit in getting a top of the line grinder to get the best grinding experience.

A good grinder will save time when grinding weed, grind the weed much finer and better, and will be much easier to work with.

Not only do we recommend investing in a top of the line grinder we also recommend to purchase a four piece grinder. Here is why?

Four Piece Grinder – What is it?

The most common grinder is not actually a 4 piece grinder but a two piece grinder. This is probably because two piece grinders are very cheap and are easy to find. Even your local gas station probably sells these grinders. A two piece grinder is just what it sounds like – a grinder that is based in two units. There is the top part and a bottom part and the herb goes in the middle. A couple quick twists and the herb is ready to be dumped out, rolled up, and smoked.

But using a two piece grinder can cause some issues:

  • The weed can get stuck between the teeth of the two piece grinder
  • The weed is not as fine as a four piece grinder making it harder to roll up and smoke
  • There is no separate compartment to smoke the kief

Fortunately having a four piece grinder can fix that! A four piece grinder is similar to a two piece grinder but has two extra pieces, hence the name four piece grinder.

If a piece of herb falls through the 2nd layer and onto the 3rd layer then it is safe to assume the piece is fine enough and is ready to smoke. This is not possible in a two piece grinder. When one empties out a two piece grinder all the contents fall, including the parts that are not completely grinded up. But in a four piece grinder, only the bottom two layers are unlocked.

The bottom layer of the four piece grinder is also very important. Even smaller bits of herb make it to the bottom of the four piece grinder. If one likes to smoke the kief this is a very cool added bonus that will make a big difference in ones smoking sessions.

Lastly, a four piece of grinder can store more weed in its chambers. Going to a friends house or out to an event? Your four piece grinder can carry more herb than a two piece grinder.
