Are you looking to acquire a weed grinder but lost among the many options available? Wondering which elements to look for while selecting the best weed grinder?

A cannabis shredder is considered one of the most basic but necessary tools for any hobbyist. Whether you vape, smoke, or consume marijuana, grinding is an essential procedure.

Have you been doing this by hand? Are you tired of lengthy and messy sessions? Shredding your weed doesn’t have to be daunting.

This comprehensive guide outlines all the aspects to consider before purchasing one. We’ll then share our reviews of the best weed grinders available.

​Quick Answer: The 7 Best Weed Grinders For 2019

What Is a Weed Grinder?

Before grinders came to life, cannabis consumers would usually shred their weed using bare hands or scissors. It certainly did the job, but you’d end up with hands covered with the precious but sticky resin.

Lucky for you, preparing your cannabis these days doesn’t have to be that difficult. The best weed grinder will make this process faster and more efficient—and definitely less messy.

Manual or electric, a weed grinder is often a circular-shaped device. It’s made to chop cannabis to your desired consistency, and ready to be rolled, cooked, or used in a vape.

What Is Kief and Why Is It Important?

Some weed grinders have the ability to separate out the kief. In order to know if this is important to you, it’s helpful to understand what this is.

Kief is a resin gland growing on the flower buds. It appears similar to fine hair, pollen or even minuscule crystals. It’s very potent and contain most of the cannabinoids found in the plant.

For most hobbyists, wasting kief is just like cutting your spaghetti in a fine Italian restaurant. It’s sacrilege.

Kief has many uses. It can be sprinkled over a joint, coffee or on a cannabutter toast. It can also be mixed in a cake for increased potency, or used in a vape or pipe. Some people even use it to make hash.

Selecting the best grinder for weed should allow you to retrieve the precious resin.

Why Should You Use a Weed Grinder?

Once you start using a grinder, you’ll wonder how you’ve managed without one until now.

The first role of a grinder is to increase your cannabis’ surface area. This means you get more out of your bud, so over time it saves you money. Grinding your weed also allows it to be distributed more evenly over a joint, or in baking.

The best marijuana grinder will shred your weed fine enough to allow more heat to pass through the plant. By doing so, it releases more THC (Tetrahydrocannabinol) and CBD (Cannabidiol), as well as flavor and aroma.

What Are the Different Types of Grinders?

There are two main types of grinders available: manual and electric.

Manual Grinders

Manual grinders need a bit more elbow grease, as grinding is done through a rotation movement. Some grinders—called rotary grinders—even come with a handle to facilitate the process.

Traditional manual grinders usually come in two to four pieces, with varying numbers of chambers. These essentially catch the different parts of the buds. We’ll elaborate on multi-chamber grinders further down.

They might not seem as convenient as electric grinders. However, the manual ones often give you better control over the consistency.

There’s also an option for grinder cards. They can be a good option if you’re looking for the ultimate portable solution. Shaped just like a credit card, they’re small enough to fit in a wallet.

Electric Grinders

These might be the most convenient type of grinder, as they get started at the push of a button. They’re a great choice for those suffering from arthritis.

Most electric weed grinders don’t include a kief-catcher chamber. Despite their convenience, this can be a major drawback for many cannabis users.

There are many different electric weed grinding products available. They’re a good option if you need to grind a large amount of marijuana at once.

Because of the electric devices’ inability to filter the kief, manual grinders tend to be the preferred method for shredding cannabis.

How to Use a Manual Weed Grinder?

Manual grinders aren’t difficult to use.

First, place your buds in the top chamber, where the teeth are. You might need to cut your buds in smaller pieces to make them fit between the teeth. For a better shred, place them on the edge of the grinder rather than in the center.

Close the lid and rotate the device about 10 times. Look through the lid (if it’s transparent) or open the grinder. If you still see pieces in your top chamber, give it a few more rotations.

Once all the pieces have fallen through, open the lid. If your grinder comes with several chambers, you’ll find your shredded cannabis in the second chamber, and the fine kief in the last chamber. This is the part that’s known as the kief-catcher.

The best weed grinders come with a scraping tool to help you retrieve the kief.

How Many Pieces Should an Ideal Grinder Have?

The number of pieces doesn’t directly correspond to the number of chambers within the grinder. For example, a 4-piece grinder has three chambers and a 3-piece grinder contains 2 separate chambers. This is because the lid is considered to be a piece.

Two-Piece

A two-piece grinder is one that contains one single compartment with teeth on both sides. It’s smaller and more compact, but often difficult to remove the plant once it’s ground.

2-piece grinders might be great options for those looking for a coarse shred. Containing one chamber, they don’t separate the precious kief.

Three-Piece

This type of grinder comes with two separate chambers. You’ll place your buds in the upper layer. While grinding, your shredded plant and kief fall into the lower compartment.

The second chamber is often used as a storage area once the grinding is complete.

Four-Piece

These high-end grinders contain three separate chambers and are usually the most popular.

The lowest compartment contains a filter, able to retrieve the thinnest particles only, such as kief. Some users keep kief safely stored in the last chamber until enough has accumulated to collect it.

This type of grinder may be the perfect choice for the most advanced users.

What Other Elements Make a Good Grinder?

What is a good grinder for weed? Let’s have a look at a few other important features and aspects to consider.

Material

When it comes to material, it’s important to look at the material of the outer case and that of the teeth. Both are important.

Wood

Wooden grinders are often hand made and difficult to reproduce in large quantities. They can be a great choice if using organic material is important for you, or if you’re looking for a more natural look.

Most wooden grinders have a single chamber. They tend to be more complicated to clean, and are typically more expensive than other types.

Acrylic

Acrylic grinders are more affordable but often less durable than other types.

They’re normally very compact and easy to carry around. Even if they aren’t the best looking type of grinder, they’re very convenient to use.

Metal

The top grinders for herbs usually provide at least two chambers and are made from metal. The best quality weed grinder will normally be made of either titanium or aluminum. Titanium is generally more elegant and durable—but also more expensive.

Many argue about whether aluminum is safe, if shavings mix in with the weed. This shouldn’t be a problem, for a few reasons.

First of all, the risk of shavings is rare. Also, vapes, pipes and lighters won’t reach the 1,218 degrees Fahrenheit needed to melt aluminum. Therefore, no harsh chemicals should be breathed in.

Easy to clean, aluminum grinders are also better at containing smells. Something to consider if you’re carrying the device around.

You’ll also find aluminum grinders that are coated with titanium.

Teeth’s Material

The teeth are the parts that will be grinding your cannabis. This makes them one of the most important elements of your grinder.

Aluminum teeth are often preferable as they tend to stay sharp for a longer period of time. Acrylic teeth tend to chip or even come off entirely, ending up in your weed for you to smoke or consume. The teeth of wooden grinders are normally made of metal, which is more durable.

Size

There isn’t a wrong or right size for the best weed grinder. It’s a matter of personal preference and use.

The smallest grinders have a diameter of 1.5 or 2 inches. More compact, they’re also the most portable. The obvious downside is that they will only shred a small amount of material at once.

Medium size grinders have a diameter of 2.5 to 3 inches, enabling them to grind more weed in one use.

It’s also important to consider the number of teeth present in your grinder. The more teeth, the more efficient your grinder will be. In general, 50 teeth are needed in a 2.5-inch diameter grinder.

Other Things to Consider

Are you looking to store your cannabis in the grinder when not in use? You might want to look for a device containing magnetic locks to keep your weed fresh and full of flavor.

The best weed grinders come with added features, such as handles or clear tops. These are very convenient when it comes to shredding.

How much is a good weed grinder? Grinders come in a wide range of prices and it’s easy to overspend. It might be best to allocate a specific budget for your grinder before you decide which to buy.

The best weed grinder if you’re on a tight budget is typically made of acrylic material and comprises one to three chambers.

How to Clean a Manual Grinder

Kief is sticky, and if not cleaned regularly, can glue and seal your grinder over time.

Place your grinder in the freezer for 15 minutes to loosen up the stickiness. It’s harder for kief to stick when frozen.

With a small brush, use isopropyl alcohol to remove the kief. If your grinder is absolutely unopenable, simply soak your grinder in the solution.

Finally, rinse your grinder with warm water, and let it dry.
