From Golden Gate Grinders to Phoenician Engineering, BestGrinder.net has done more herb grinder reviews than any site on the web. So we were surprised when we found a prominent grinder brand that seemingly slipped through our grinder reviewing fingers. This is the case when it comes to Masterdam Grinders. Founded in Amsterdam, Masterdam has been putting out quality herb grinders since 2014 and is a well established brand, selling grinders on the Amazon marketplace, Amazon UK, and other online and offline shops around the globe.
Let’s dig deeper and see what exactly Masterdam grinders offer that help them stand out from other herb grinder brands in what has become a very competitive market.
The vaporizer market has truly revolutionized the way in which you can consume your stash. With discreetness and less harmful chemicals, it has become the most popular way to enjoy herb. That being said there are some things about vaporizers that some smokers may not like.
First, vaporizers take out a lot of the flavor that comes from the herb. The truth is that many of us like the flavors from cannabis and find this to be a disappointing aspect of vaporizing. Second, you have to deal with temperature settings and charging the battery of a vaporizer which can become cumbersome.
For those of you who still want the full experience of smoking, but without the unwanted burning and coughing, Genius Pipe has the product for you. Genius Pipe is a pipe that brings a lot of new features to the table to enhance the pipe smoking experience.
One thing about herb grinders is that almost all of them seem to have a similar design and shape. There may be slight variations between each model in terms of teeth shape, size, number of pieces, etc., but at the end of the day they use the same basic principals to grind your herb. This entails putting the herb in the top chamber of the grinder, and turning the lid so that the teeth grind your stash to perfection.
In general, I go by the mantra of if it isn’t broke, don’t fix it, but that doesn’t mean that the herb grinder market couldn’t use some fresh ideas. For any readers would like a new take on herb grinding, the folks at PenSimple have got you covered. They have completely reimagined the herb grinder and come up with the PenSimple Grinder. It looks totally different than your run of the mill four piece aluminum grinders, and because of this has some unique features.
As with the namesake of the PenSimple, the shape of this grinder is akin to a pen. This makes it easy to hold and manipulate so that you can aim the herb with precision. Dimensions for the PenSimple are 7″x1″x1″ with a weight of only 4.3 ounces, making it very lightweight compared to typical aluminum weed grinders.
There are four pieces that attach with the PenSimple Grinder. As with standard grinders, the PenSimple has a grind chamber made up of a lid with teeth and bottom with holes to allow the ground herb to fall through. With PenSimple there are only a few small teeth on the lid, but none on the bottom part of the grind chamber, like you see with typical herb grinders.
It is important to realize that the PenSimple does not grind your herb for you. This is still a manual process.
What it does do is help to dispense the ground herb out of the tip making it easier to get the herb in your joint or bowl without spillage. With a simple push of a button your ground up stash is neatly dispersed with pinpoint accuracy. I love this feature, and is certainly a step up from typical grinders where you have to use your fingers or scraper tool to manipulate the herb.
PenSimple Grinders are made of aircraft-grade aluminum, meaning this thing is built to last. We are glad to see PenSimple use such quality materials on their grinders as it shows they take quality seriously. Another positive is that it doesn’t appear that PenSimple’s design requires any glueing of components, making it less likely that any individual part will break loose.
Three Different Grinder Modes
Unique to the PenSimple Grinder is the flexibility of having three distinct grinder modes. The three grinder modes are full, maximum-storage, and direct-grind.
This is default mode of the PenSimple. Load the herb in the grinding chamber, and once ground it is ready to be unleashed at the push of a button.
For when you are traveling, or on a hiking trip having the maximum amount of herb ready to go is a must. Maximum-Storage Mode allows you to store up to 3 grams of your finest herb by removing the top and bottom grind teeth. In this mode you cannot grind any additional herb.
Direct Grind Mode
Take out the storage compartment and then you have an efficient grinding machine. This is perfect for when you want to keep a small stash fresh and grind on the go. This mode holds up to .25 grams, but can be ground on command and still dispensed using the electric point and shoot tip.
What PenSimple Should Improve
In the future, PenSimple should strongly consider adding an electric element to the herb grinding process. Having both an electrical grinding process and the automatic dispensing tip would go a long way to set the PenSimple apart.
Another issue with the PenSimple is that the 1 inch diameter design creates an environment where it is easy for herb to clog the unit. PenSimple will have to choose between keeping their grinder portable-friendly with a frequent cleaning requirement, or to make the diameter larger meaning the grinder would become slightly less portable.
PenSimple has made some bold innovations to the herb grinder, and as such you can expect to pay more for this grinder than your average four-piece aluminum grinder. At $60, the PenSimple is not a bargain, but is cheaper than premium American Made grinders like Phoenician. This is a reasonable price point for this product.
The Final Grind
PenSimple has changed the herb grinder game with its point and shoot design. This certainly makes filling your bowl easier than ever before.
We wish that PenSimple would have added an electric grinding component, and are surprised that the actual grinding process is still manual.
Whether this is a good choice for you will depend on how much you value the point and shoot electric dispensing feature. If this is a big deal to you, then the PenSimple is really the best choice. However, for those who care equally about other functions like storage capacity, grind quality, and grinder jamming, we recommend you look at conventional high quality grinders.
One of the hottest selling herb grinders to hit the market in recent months is the Kozo Herb Grinder. This grinder has been selling so well that it appears that Kozo has had a hard time keeping it in stock. The reviews for this herb grinder are also stellar leading to a good reputation.
At BestGrinder.net we like to dig a little deeper to see if the sales volume and reviews match up with the quality. Let’s take a close look at the Kozo Grinder’s pricing, features, and quality.
The Kozo Grinder is no doubt a good looking herb grinder. I personally like the black and white lines that are included as design elements on the outside of the Kozo.
Another feature on the outside of the Kozo Herb Grinder is the indents that span vertically from the top of the grinder to the bottom. These are part of the herb grinder to enhance the grip so that you can twist the lid with greater ease. The more grip you can get the more grinding you can do, its that simple.
Kozo Grinders feature square shaped teeth that have sharp edges to help break up herb. I’ve mentioned before that I like diamond-shaped teeth similar to those featured on Black Tie Grinders. Diamond teeth do a better job at shredding herb with the least amount of force.
That being said, the teeth on the Kozo Grinder are not bad and will work for most herb fans. For those who are serious herb connoisseurs you may want to find a grinder with diamond shaped teeth.
Other Design Components
Kozo has had a round of updates in an effort to improve upon their original herb grinder. This update primarily includes an increase in the height of the walls on the removable herb collection piece so that the Kozo Grinder can hold more herb.
Kozo Grinders come in a single 2.5 inch diameter size. This is the most common size for personal use herb grinders and should satisfy the vast majority of herb grinder users.
It appears that Kozo varies the price of their herb grinder frequently. I’ve seen the Kozo Grinder priced anywhere from $20 to $24. If you are set on getting a Kozo Grinder and see that it is at the higher end of that range it may be worth waiting a few days before buying to see if the price drops.
Kozo currently only comes in black. Certainly a choice that will work for most, but not exactly exciting. Hopefully in the future Kozo will expand their offerings to include more colors.
The KozoGrinder is most similar to The Rocket Grinder in terms of quality and styling. Both are fine grinders, but not the best of the best.
Kozo Grinders feel solid in your hands and do have a smooth turning action, which is a big plus. If they’d switch over to diamond shaped teeth this grinder would be really hard to beat.
The vast majority of reviewers have been happy with this grinder, with a select few mentioning that the bottom set of teeth fell out after a few uses. This is a common issue with grinders made from two pieces of aluminum that are glued together.
For those who are unaware the reputation of Amazon’s reviews have taken a beating lately. Some sellers are using unethical tactics to get unwarranted positive reviews. This means you may end up buying something that isn’t what you expect in terms of quality.
Does this mean you shouldn’t buy a Kozo Grinder? No, but you should realize that their current rating on Amazon is likely inflated.
Kozo Grinders do not come with many extras. Their grinder box does feature their logo, but is a simple brown cardboard box. Included with your purchase is a pollen scraper which is common with most herb grinders.
What We Like About The Kozo Grinder
Updated design allows for the grinder to hold more herb
Priced fairly reasonably and similar to the competition
Has indentations for your fingers which enhance grip
What We Don’t Like About The Kozo Grinder
Square teeth are simply inferior to diamond teeth
Uses two pieces of aluminum which means the bottom set of teeth may fall out over time
Vape pens are the ultimate in portability when it comes to the modern consumption of herb and waxes. Unlike their larger portable vaporizer counterparts, vaporizer pens are thinner, similar to the thickness of a cigar.
Vape pens are usually cheaper than portable vaporizers and have less features. This is what you sacrifice for the extra portability and discreteness.
As the vaporizer industry continues to grow, big names in the music industry have begun to partner with vaporizer makers to create exclusive product lines.
Atmos has jumped into a partnership with the rapper Tyga to promote the Tyga X Shine Pillar Kit. For those who are unfamiliar, Tyga is a successful rapper currently signed with Def Jam and has had several charting hits.
At the end of the day, it is the quality of the vaporizer that matters no matter who’s name is on the packaging. While we think partnerships are good for marketing, they often do not speak to the quality of the product. Below we give you an in depth look at our thoughts on the Atmos Tyga Pillar Vaporizer.
It has been awhile since we have reviewed an herb grinder, so today we are going to provide an in depth look at the Rocket Herb Grinder. This is the Rocket Herb Grinder sold on Amazon, and not the other Rocket Herb Grinder that is motorized.
We are traditionalists when it comes to herb grinders because we feel that the four piece grinder design is pretty much perfect. Adding batteries and motors to herb grinders seems to us to be a gimmick and just makes the grinder easier to break.
Rocket has been selling their weed grinder for less than a year at the time of this writing. However, we have been impressed with their popularity and they have maintained a rating of over 4.0 with more than 50 reviews.
The first thing we noticed about the Rocket Grinder is the cool design. The silver colored accents on the aluminum outer body give the grinder a cool look that stands out from the competition. We also like the indentations on the lid that give your fingers a place grip increasing the user’s leverage to grind herb with greater force.
The Rocket Herb Grinder features 26 square teeth that have sharp edges. We’ve discussed before that we prefer the diamond shaped teeth of other grinders as they generally grind better.
That beings said, some smokers may prefer the grind provided by square teeth. If you don’t want to have too fine of a grind, then the Rocket Grinder may provide the herb consistency you are looking for.
Other Design Components
The kief filter does not screw on to the grinder, but simply fits into the kief catcher chamber. Whether you like this design is a matter of personal preference. Generally, we like to have a screwed in filter screen as it allows for a wider screen that more effectively filters herb.
The Rocket Herb Grinder comes in one size, which has a diameter of 2 inches. This makes it slightly smaller than similar grinders that are usually 2.5 inches in diameter.
If you are looking to grind a lot of herb then you’ll want to look into buying a different herb grinder, but if you are a casual smoker then the Rocket Grinder will likely grind enough herb for your needs.
In the future, we hope that Rocket Grinders will consider making a larger size grinder option.
The Rocket Herb Grinder is quite affordable, and is priced around $25. This makes it a great grinder for anyone on a budget who wants to get something better than a cheap acrylic grinder. For those not wanting to spend more than $30 on a decent herb grinder, the Rocket Grinder should be on your short list along with the Golden Gate Grinder and Black Tie Grinder.
You won’t find much variety with the Rocket Herb Grinder as it only comes in the black color. This is the case with many up and coming weed grinder brands, so if color is not an issue for you then the Rocket Grinder is still worth consideration.
The Rocket Grinder does perform well. It produces an even herb consistency that is a bit thicker than other grinders with more teeth.
A strength for the Rocket Grinder is the lid magnet. The Rocket Grinder has one of the strongest lid magnets out of all the grinders we have tested. You can rest assured that you won’t spill your herb with this grinder.
On the flip side, the Rocket Grinder does have a two piece lid that can lead to breaking over time. The best aluminum grinders have one piece lids so that breaking is a non-issue.
Rocket Grinders offers a 100% money back guarantee. This allows you to buy with confidence knowing that they will offer you a refund if you are not completely satisfied with your Rocket Grinder’s performance. Thankfully, this has become the industry standard for herb grinders on Amazon, and most now offer a money back guarantee.
Included with your Purchase of a Rocket Grinder is a gift box, velvet bag, and plastic pollen scraper. When it comes to grinders, Rocket Grinder has done a good job adding in some nice bonuses to your purchase which increases the value of this herb grinder.
What We Like About Rocket Grinder
Cool and modern design sets Rocket Grinder apart from the competition
Comes with a lot of extras like a carry bag and pollen scraper
Lid has spaces that fit fingers for better grinding leverage
What We Don’t Like About The Rocket Grinder
At 2″ in diameter, the Rocket Grinder is a bit smaller than many similarly priced competitors
Only has 26 teeth which do not grind as evenly as other grinders with more teeth

With so many herb grinders that look damn near identical to one another it is refreshing to see a company like After Grow take design seriously. Their Thorinder Grinder offers a unique take on grinder design and makes it stand out from all the other weed grinders for sale today.
After Grow has a website that is as unique as their grinder. Check it out if you want to do additional research apart from this review.
With the unique branding around Thorinder it is surprising how little social media is being done around this product. Searching Youtube there are only a few decent videos reviewing the Thorinder, and to date they have less than 150 likes on their Facebook Page.
On top of this the Thorinder is not a top selling herb grinder on Amazon. Let’s dig a bit deeper to see if we can find out why this grinder isn’t getting more attention.
Without a doubt one of the most interesting characteristics of the Thorinder Grinder is the hole pattern. Most herb grinders have a hole patterns that are exclusively made up of little circles that allow for the herb to fall to the second chamber.
That is not the case with Thorinder. The first set of holes are actually shaped like lightening bolts, which does give the grinder cool styling and sets it apart from its competitors.
However, from a functional perspective these special design features do little to improve the actual grinding experience. And with an expensive price tag it is important for Thorinder to not only look different but to perform differently from cheaper grinders.
The teeth on the Thorinder are some of the best we’ve seen on any herb grinder. This is where the Thorinder really excels. You can tell that the teeth were design for optimum grinding. The teeth that align the lid are curved with sharp ends similar the curved teeth found on some sharks.
On the second piece of the Thorinder are teeth that are shaped similarly to a comma. What we mean by that is there is one side of the tooth that is sharp while the other side is flat.
Putting these two teeth designs together makes for a beautifully ground herb that is even and ready to smoke.
Other Design Components
There are several design components that are unique to the Thorinder.
First off, the Thorinder has a smooth finish on the outside, which is certainly different from the traction embedded design that most other herb grinders feature to enhance grip. We are not sure why the makers of Thorinder decided to not have traction on their grinder, but for most it will not make a big difference.
As you can see from the pictures, the lid of the Thorinder actually has a clear top so you can actually watch as your herb is ground. Another feature that we don’t feel is necessary, but does make the grinder look cool.
Price is where Thorinder becomes a pretty divisive grinder, and why we believe the Thorinder does not sell well overall.
If you check on Amazon, currently the Thorinder grinder is selling for around $50.
While there are certainly more expensive grinders out there, including Phoenician and Compton, those grinders have several features that stand out from Thorinder. Some of these features include removal screens, being made in the USA, and top notch machining.
Unfortunately, Thorinder is a great looking herb grinder, but just doesn’t have any features that really make it function exceptionally better than a grinder that is $20 cheaper. This is why we would consider looking at some other less expensive options if you are more concerned with the function of your grinder and don’t care as much about styling.
Thorinder does offer some variety in regard to color.
As you can see from the picture to the right the Thorinder comes in five different inside color options including gray, white, orange, blue, and black.
We hope they had a few more colors in the future as we think green and purple would look really great.
Thorinder comes in the standard 2.5 inch diameter size and a “mini” size. For most, the 2.5 inch standard size Thorinder is the way to go as the mini may not hold enough herb to meet the needs of many smokers.
Thorinder grinder does perform well when it comes to the task of grinding herbs. You will get a nice even grind with plenty of kief left over when you use this grinder. We attribute the above average grinding ability of the Thorinder to its unique teeth design.
That said the Thorinder will stick and build up residue over time and will need cleaned on a regular basis. While typical of most grinders, it is bit more noticeable than we’d like for a grinder in the Thorinder’s price range.
One feature from After Grow that we’ve seen from no other weed grinder manufacturers is the ability to buy individual grinder pieces separately. If you go to the parts section of the Thorinder website you can see where you can buy the individual pieces.
This is actually pretty helpful if you happen to break a piece of your Thorinder Grinder and don’t want to spend the money to buy a completely new unit.
Another cool way that Thorinder stands out from the crowd.
After Grow’s Thorinder Grinder has the most impressive gift box we’ve ever seen for any grinder. It is heavy-duty and presents a good amount of showmanship to the unboxing experience. Check out the video above if you want to see how the gift box opens.
The Thorinder also comes with a top-quality guitar pick scraper that will help you sift through herb and kief.
What We Like About Thorinder
Very cool design and syling makes the Thorinder stand out from the crowd
Teeth design is customized and works great when in use
Gift box is amazingly high quality
Can buy grinder components separately
What We Don’t Like About Thorinder
Too expensive for the performance
May need cleaned more frequently than other grinders
When you really think about an herb grinder, it is different in many ways compared to other weed accessories or tools. In fact, I’d argue that weed grinders most closely resemble a sort of kitchenware. Herb grinders are designed to grind herbs after all!
A brand called SLX Grinders has taken inspiration from other kitchenwares to improve the performance of the standard herb grinder. They’ve done this by using non-stick material ceramic coating over the aluminum four-piece grinder.
As a brand SLX is active in social media and can be found at some industry trade shows promoting the unique benefits provided by their non-stick herb grinders. It is apparent that they are truly committed to their product and making improvements.
With so many grinder brands out there today it is easy to get overwhelmed by all the choices. Thankfully, we will help you take the guess work out when it comes to SLX Grinders so you’ll have the information you need to make a well researched purchase.
As mentioned previously, what really sets SLX Grinders apart from the competition is the ceramic non-stick coating that is meant to help prevent herb from sticking to the wall of the grinder, making it more difficult to turn the lid.
What we really like about this non-stick coating is that it does not include any potential toxic substances like teflon or PTFE. There are so many potentially dangerous materials that are secretly found in your cooking and smoking accessories (FYI, the dangers of using aluminum grinders is a myth) it is nice that there is peace of mind when using an SLX Grinder.
On a more disappointing note, the non-stick coating does not work as well as we’d hoped. Not only did we notice this, but other users also have commented that the non-stick coating does not work as advertised. We hope that SLX continues to improve the coating so that in the future it works better.
At the end of the day you may not be completely satisfied if the main reason you are buying an SLX Grinder is for the non-stick coating.
The SLX Grinder has more teeth than any other grinder we’ve reviewed relative to its size. The grinder has a diameter of 2.4 inches and features an amazing 55 teeth! To compare, the top rated 2.5 inch Black Tie Grinder has 50 teeth, which is great on its own, but not up to par with the SLX.
Personally, we don’t love the shape of the teeth on the SLX. They have more of a square shape with sharp edges on one end. Through our testing at BestGrinder we’ve found that diamond shaped teeth tend to perform best at shredding herb.
Other Design Components
Looking a bit closer you will see that the rest of the components found on the SLX Grinder are consistent with other top of the line grinders.
SLX Grinders come with neodymium magnets that work to keep the lid on while grinding herb so that there are no spills.
The aluminum used in SLX Grinders is aircraft grade and made to last a lifetime.
Lastly, the micron screen is the perfect gage to maximize kief production. Not only that but the screen is simply placed in the grinder without having to be screwed in, making the SLX 20% shorter than standard four-piece grinders, which enhances portability.
It is safe to say the features and design of the SLX are in the upper echelon of herb grinders. Due to this you should not be overly surprised that the SLX costs a pretty penny.
In fact, the SLX Grinder is one of the more expensive grinders we’ve ever reviewed, with the home-size coming in at a price point of around $60.
Even with the unique features, it is hard to justify spending this much on the SLX. Outside of the non-stick coating, most of the other features can be found on grinders that run $30. Given that the non-stick coating has not yet been mastered by SLX, it may be worth considering other cheaper options that do not have the non-stick feature.
This isn’t to say that the SLX is a bad grinder by any means. On the contrary, the SLX is a great grinder. It just isn’t the best value.
If you like color and size variety in your herb grinder, then SLX has you covered.
Size-wise, the SLX comes in two versions: the smaller pocket-size (2 inch diameter) and home-size (2.5 inch diameter). If you plan to take this on the road and grind small amounts of herb then consider the pocket. Otherwise, we’d go with the larger home-size as it is still not huge.
If you are like us, you like your world to be a bit more colorful. Having fun colors in your life perks you up and gets you excited for the possibilities of the day.
SLX Grinders must share this mindset as well as they offer their grinders in many different colors. Currently, SLX sells their grinders in the following colors: silver, gray, yellow, purple, green, black, and gold. With all these color options you can get the perfect SLX that fits your personality.
The SLX Grinder performs very well save for the non-stick coating. It is not to say the non-stick doesn’t work, but it just is not significantly better than other grinders.
However, when it comes to grinding herb and collecting kief the SLX is the real deal. The 55 teeth make shredding a breeze, with the finished product being an evenly ground herb.
SLX states on their website that if your grinder is damaged or breaks during normal use that they will send you a replacement part at their discretion.
Note that it would be wise for you to take a look at their replacement policy because SLX is fairly specific about which resellers are considered legit. If you buy from someone outside of these resellers or SLX, then SLX clearly states they will not honor any replacement claims.
The SLX does not come with a ton of extras.
You do get the typical scraper to help you sift through kief. However, you won’t find a carry bag or any fancy gift box with this grinder. Hopefully, they’ll add these in the future as most other grinders at this price point do offer some pretty neat extras.
What We Like About SLX
Non-stick ceramic coating contains no toxic chemicals or ingredients
SLX Grinders come in many different sizes and colors
55 teeth is the most we’ve seen on a standard size grinder
Grinder components are good quality
What We Don’t Like About SLX
Non-stick coating doesn’t work all that well
SLX Grinders are expensive
No extras come with SLX Grinders
The Final Grind
SLX is built on a great concept of developing an herb grinder that is non-stick. As you know many herb grinders get gunk built up over time making them difficult to use and require frequent cleaning.
Unfortunately, SLX has not mastered the technology to create a non-stick herb grinder and what is left is a very overpriced average herb grinder that does not have anything particularly special going for it.
