Best Weed grinder guide
(Last Updated On: May 2, 2018)

Tested by time, the Space Case brand has built its reputation because of its high-quality and reliable line of dry-herb grinders. Made of aerospace aluminum and titanium coated, the Space Case simply excels among many of its competitors. The body is made of high-quality material, so it is durable enough to withstand impacts without being damaged.

The Space Case grinder has Strong Magnetic Lids. So, the lid stays on even when exposed to greater force. It allows the buds to stay in place, avoiding wastes. But despite the strong magnet, you can still easily spin the lid because of the thread design. It also has sharp teeth that grind the whole herbs finely. The sharp diamond teeth allows you to slice through the thickest dry herbs with ease.

And because the Space Case is lightweight, you can carry it around so conveniently. Plus, it features Teflon-grade O-rings that make the device ergonomic even to those people with arthritis. It helps the device to not cause friction when you are grinding it. This results in a much smoother overall performance.

The Space Case comes in three sizes. So you have more time to decide which size fits your vaping needs. The 2-piece is the simplest option, while the more expensive 4-piece offers more functionality. The four-piece Space Case grinder has kief screens made for pollen collection in the bottom compartment.

What needs to be improved in the Space Case is the tendency for residue to build up inside the device. You’ll notice material can also get stuck atone time. This, however, is a common issue among the grinders in the market. In the meantime, tapping the device after every use is a quick yet temporary fix. Maybe some nonstick grinders next time? But overall, the Space Case is one brand of a grinder that is here to stay for a long time. Thanks to its superb quality and outstanding reputation.

Weed grinder and vaporizer are as inseparable as bread and butter. And as dry ground cannabis becomes the staple go-to among connoisseurs, we just cannot let weed grinders go unnoticed.

What Really is a Weed Grinder?

Best Overall Weed Grinder

Based on: Performance, Quality, Cleaning/maintenance, Probability, Easy of use, Warranty, Price.

Kannastor Grinder 

The Kannastor Grinder is your type of herb grinder engineered to make grinding weed easy and efficient. In terms of material used, the manufacturer invested in aerospace technology in making this particular product. Therefore, if you are considering a grinder with a highly durable design, this is the way to go.

A bit cheaper than most grinders in its class, this makes the Kannastor grinder our top pick among consumers.

It has an efficient design that lets you avoid problems such as pollen and resin that stick to the grinding teeth. And because of this, it also makes maintenance quite a breeze. It also has a replaceable screen which helps prevent hard maintenance concerns. The 4-piece version measures 2.5 inches, while there is also the full 8-piece grinder under its GR8TR line.

Upon unboxing the Kannastor Grinder, you’ll notice its sleek and minimalist design. It also allows you to peek how much herb you have since it has been actually as a clear jar unlike other herb grinders in the market.

It has a screw in the mechanism that gives you the option whether to produce a coarse grind or a finer grind depending on what you actually prefer on your vaporizer. In terms of performance, the Kannastor Grinders can ground the herb just enough that the herbs don’t also burn too quickly once you started vaping.

What stands out the most on the Kannastor grinder is its grinding compartment’s aluminum teeth found in the lid and the bottom. It efficiently takes your material into smaller pieces. It is also worth mentioning that the screen has the right sized holes that allow the crystals to pass. 

If you’ve felt frustrated about cleaning your grinder, then this isn’t an issue when using the Kannastor grinder. All you need to do is to replace the screen, and you are all set. You’ll just need screen pliers to remove or replace the screen.

As we enter 2018, Kannastor has released the Kannastör GR8TR V2 Series Grinder which we believe is the world’s most advanced grinder up to date! 

Made of anodized, 61/60 food-grade aluminum, you can be sure the device is strong enough to withstand falls, knocks, bumps, rugged conditions, extreme temperature changes and every stress imaginable. Such durability and strength mean you can take the Kannastor GR8TR V2with you while camping or on your favorite trips.

What makes the GR8TR V2 unique is the absence of the rather traditional teeth.

Instead, it comes with 2 interchangeable plates you can choose — whichever type of grind you like.

The standard plate produces medium-coarse grind. This is ideal for your everyday vaping sessions.

But for the connoisseur, the special vaping plate results in a much finer consistency.

The greater surface area around the finer particles means more even heat distribution. This requires a lesser frequency of stirring the herbs inside the chamber.

Plus, the denser flavors just give you that ultimate vaping experience.

Of course, we love Kannastor GR8TR V2’s modular design.

Just below the place the removable fine mesh screen used to filter the fief for your pleasure.

The contoured edges of the base give the device a streamlined design. It also has a pick tool to help you collect your herbs down to the last bit. A modular design makes it so easy for you to clean and maintain your GR8TR.

For greater flexibility, the GR8TR V2 offers your three options: the solid screen with its sleek body, the glass jar option so you see the inner works and content of the device, and the more compact option for portability. There’s no reason you won’t love any one of these designs!

Best Quality Grinder

Mama P’s Grinder 5-mama-ps -best weed grinders

The award-winning Mama P’s Grinder owes its fame to how it’s made with durability and style in mind.

Each piece is made from top recycled aircraft quality aluminum material. Of course, other counterparts use similar materials, but the makers of the Mama P’s seemed to have successfully brought such hype to a higher level.

This product is so popular that it won First Place for Best New Product during the High Times Cannabis Cup in Los Angeles, Detroit, and Denver.

These times, the Mama P’s grinder is now synonymous with the words classic and authentic: an all-American product you rightfully deserve.

So, if you are looking for precision, durability, and grinding herbs into small pieces, this piece of grinder might just be what you need.

The Mama P’s is a four-part herb grinder that has an included lifetime warranty upon its purchase. That’s guaranteed superior quality all over. 

The bottom component of Mama P’s Grinder also functions as a kief catcher that collects pollen dust that goes through the replaceable screen. It also has 57 diamond cut teeth for better grinding results.

According to the manufacturer, this weed grinder has been crafted in the US and has been inspected 10 times before it was approved. 

It is also best known for its ergonomic design which has even been praised by people who have arthritis. Inside the kit, you’ll also find a magnetic lighter to complete you experience as a connoisseur.

Also included is a replaceable 60-micron titanium screen that has been hand wedged in each grinder, allowing you to replace the screen if it ever gets damaged. 

If there is one downside of the Mama P’s Grinder, it’s the price tag.

The above average numbers could mean even those who like the product so much might just look for something else. In fact, the cheapest is already at the same price as the Space Case and Kannastor grinders. But here’s what we’re all sure about: You’d definitely get your money’s worth with the Mama P’s Grinder!

Aerospaced Grinder

While the best grinders don’t need much rocket science to prove their worth, the Aerospaced Grinder definitely grabs attention with the grinder’s name itself.

Indeed, this piece of contraption is more than just ordinary.

The Aerospaced body is made of anodized aerospace-grade aluminum that’s CNC milled from a solid block.

With such superb material, the Aerospaced grinder simply means every bit of our dry herbs is in good hands.

Many other grinders, on the other hand, feel more like a toy rather than a serious tool for the everyday connoisseur.

With some added features not found in other grinders, the Aerospaced Grinder goes beyond build and reliability.

Some helpful features include dual functionality of the cover, which also serves as the grind plate.

It also magnetically attaches to the lower grind plate. The extremely sharp teeth easily grind away even the most robust botanicals, resulting fine texture.

This is important if you want to get the most flavors form your dry herb.

In all, the Aerospaced Grinder exceeds our expectations in terms of performance and quality.

You just can’t go wrong with it.

Santa Cruz Grinder

best weed grinders

Going for mid-priced grinders doesn’t always mean sacrificing quality.

With the Santa Cruz Shredder herb grinder, you’ll never have to miss out on having those finely ground herbs for your vaping pleasure.

So say goodbye to acrylic contraptions that don’t last long as you would expect.

The Santa Cruz Shredder herb grinder is made of an aluminum material. This means higher resistance to breaks and scratches.

This grinder comes with a unique tooth design in that veers away from the common diamond shape.

This results in better texture and finer results each time.

The Shredder also comes in a few different sizes and a number of colors & finishes.

The four-piece grinder has three different chambers. The top and the center are attached to each other. Inside, ground herbs fall through and into the bottom part, which collects the fine produce, ready for vaping.

The stainless steel mesh inside screens smallest particles, so pollens and other foreign materials don’t get through.

Another interesting design of the Shredder is the unique thread pattern and magnet, which work to keep your herb in place.

The magnet allows everything in place while you grind in either clockwise or counter-clockwise direction.

Then the thread prevents the internal parts from grinding against each other. Then come the little things that make the Shredder so easy to use. It sports an added grip by the side for easy handling.

Our final verdict for the Shredder? You get true value for your money!

Grinder Card 


best weed grinders If you are looking for the simplest construction that can get the job done, the Grinder Card is a great option for you. This type of vaporizer is an unconventional approach to the typical round-shaped grinder design that has become popular in the market recently. This credit card sized grinder fits in your wallet and is considered a discreet weed solution by a lot of weed users today.

Made of medical grade stainless steel, it allows you to grind your material without the threat of having any aftertaste due to the material used on the grinder. It is also easy to clean because of this. You can clean this grinder using alcohol.

It also isn’t rocket science to operate this herb grinder. This grinder works exactly like a cheese grater. By simply placing the material on the surface of the grinder, you can already get your herbs in its finer version ready for vaporization or even for your roll.

This herb grinder features dual grind surface. It allows the sure to have either fine or medium grind depending on what you really prefer.

Unfortunately, its design can also have its drawbacks. For one, it doesn’t save your kief. For serious vaping connoisseurs, that’s a deal breaker. In addition to this, it takes more effort to grind the herbs on the Grinder Card than other conventional options out there in the market.

Unlike other brands that have a collecting basin, you will have to improvise on this particular product. It is important that you have a clean surface or paper that collects the material underneath. And lastly, though you can keep it in your wallet, this device can be a bit messy.

For a lot of users, the Grinder Card isn’t their primary grinder. Instead, they only make use of this product as an alternative when they are not at home. 

Things You Need to Consider Before Buying a Grinder

Over the years, the number of grinder card brands has increased. And with all the choices out there, you’ll never know which one is truly the best unless you arm yourself with enough information.

And just like vaporizers, grinder cards need to be durable and functional too to maintain you superb vaping experience.

So, before you hit that “add to cart” button, consider the things you really need in a weed grinder. Here are some points to remember:

Grinder Sizes

You may have read these options somewhere, but is choosing between these two options really important? Our take on this is yes, it is.

To get to the details, here are two questions you need to answer:

Are you the serious connoisseur?

For seasoned vapers who always want something more from just the ground herbs, kief is a serious thing.

It’s the sticky buildup that accumulates inside the collection chamber of a grinder. These resinous trichomes in cannabis is rich in cannabinoids and are more potent than the dry herbs themselves.

What kind of vape enthusiast are you?

Do you also collect the kief? According to Wikipedia: Kief refers to the resinous trichomes of Cannabis that may accumulate in containers or be sifted from loose, dry cannabis flower with a mesh screen or sieve. In other words: Kief is the THC-rich resin that falls off the herb when grounded into small pieces.

That said, you can’t collect this residue when using only a grinder card. So you need a device that collects this material too.

There are 3 types of grinders:

2 Piece Grinder2 piece grinder - Best weed grinder

Also known as a 1 chamber, have only one designated area where your weed is being grounded.

Because of the 1 compartment, the ground herb might be in different sizes which can make the grinding process longer.

Once your first round of grinding, you should open and see if any big bud sizes need to be re-grind.

3 Piece Grinder 3 piece grinder - best weed grinders

Also known as 2 chamber grinder, has an additional compartment that sits right below the grinding surface.

This compartment collects all the fine herbs that fall through when the weed doesn’t break down enough.

 

4 Piece Grinder

Also known as 3 chamber grinder, has a third area: the kief catcher.
4 piece best weed grindersAs mentioned before the kief is the THC-rich resin(small crystals) that falls off while grinding. With other grinders, you simply don’t have the option to collect those THC crystals, and as a result, they do not get smoked. With the 4 piece grinder, you are able to collect all these goodies that fall to the bottom.

To quickly summarize it: If kief is one of your priorities, it’s a good idea to choose a 4-piece grinder that has a mesh screen on its lowest compartment. This screen helps to collect the resin that falls off the bud.

On the other hand, if Kief isn’t your priority, then you can always stick to the 2-piece weed grinder set up.

Performance

The number one consideration that you have to make is to choose a high performing grinder that meets your needs. Though there’s no general rule on how to define performance.

Though there’s no general rule on how to define performance.

If you are serious about vaping, it is imperative that the herbs don’t end up too small to get easily burned, as well.

Quality/Durability

You can always view grinders as a long term investment whether you like rolling your herbs or you plan on using the most expensive vaporizers. It is crucial that you check the overall durability of the item whenever you decide to get one. Is it going to last for a good number of years? Is it made of a durable material or just some crappy plastic?

Do the teeth in time become blunt? Highest quality products don’t have this kind of problem. In fact, you won’t have problems grinding the huge amount of herbs at the very same time.

Ergonomics

A lot of people forget about ergonomics. Does it have extra grips? Does it slip in your hands when you use it? Keep in mind that not everyone has strong hands that can handle the most complicated designs. This is especially important especially for people with arthritis taking medical cannabis for their condition.

The good news is that manufacturers today are very particular how they design their products. It is just as important to take into consideration any difficulty users are going to have when using the product.

Portability

Vaping attitude has changed over the years. Nowadays, portable vaporizers have become popular. Gone are the days when vaping can only be enjoyed in someone’s basement.

Because of this trend, the demand for portable vaping also increased and so is the need for portable grinders. Unfortunately, not all grinders are convenient to use outside.

There are those that are somewhat bulky and can even grab the attention of other people. Fortunately, some versions can be kept in your wallet and can be used just the same as a cheese grater. Unfortunately, this setup usually doesn’t have the ability to collect the kief.

Price

Always remember that price isn’t the only consideration that you need to look into.  However, also keep in mind that it remains as an important factor that you should check if you decide to ever invest on herb grinders.

But of course, always remember that the cheapest isn’t always the best option. The same goes for the most expensive option. To get the best value for your money, always consider other features of the product. Does it have a warranty? Does it fit your needs? Is it really durable?

Maintenance

It is always a good idea to have a clean grinder.

But the reality is entirely different. A lot of herb grinders in the market can get messy especially after it has grounded your herb. Herb enthusiasts encounter problems such as materials getting stuck in between the teeth of the grinder.

For this scenario, make sure to use materials that can minimize all the mess. Some materials leave less mess especially when you consider the removable screens that can be cleaned. It is a good idea to check if the screens can be replaceable. 

Warranty

Some products have a lifetime warranty. For others, it only has a warranty up to a certain time.

Regardless, warannty gives you peace of mind and is guaranteed to work by the manufacturer. It is also a good measure up to when can the herb grinder keep up and perform as expected.

As a consumer, you should always be smart on how you judge an item you plan to buy. Remember pricing can be determined by several factors including marketing. Some brands will be more expensive than others because of branding or because of the hype built around it.
