The 15 Best Grinders That’ll Prevent You From Ruining Your Good Weed
There’s no sense in holding onto a crummy grinder when there are plenty of better options out there.
Sans a decent grinder, you might as well chop an entire gram in two, stuff one half as is into a rolling paper, and throw the other half into the garbage. Good grinder blades will seamlessly cut through your dry herb, sifting out the bad chunks and preserving the extra-potent pollen. They’ll create a little mound of fine, fluffy weed to roll, vape, or hell, bake into a cake. No dirty smoke, no lost product, not a bit of that eighth wasted.
You can seriously invest in this kind of accessory if you want, but you can also find some solid, inexpensive options. These 15 weed grinders—many of them with four pieces to grind bud, sift pollen, and store the results properly—each have their own strengths. One ought to suit your cannabis-consuming ways. And we’ll take the opportunity now to pair this guide with an always-timely reminder to smoke responsibly. We don’t mean legally (we’re no sticklers for the word of the law when that law itself is outdated and discriminatory). We mean, choose to support grassroots legalization and social justice efforts in the cannabis industry, and buy from dispensaries owned by minorities and companies that give back to communities when possible. Now, onto the grinders.
Just because it’s cheap doesn’t mean it’s crap. This zinc alloy grinder comes with five pieces—including two mesh screens to sift pollen from your weed, and a little scraper to use for the catch tray so not a speck is wasted—with sharp teeth and a magnetic seal. If it seems too large, then remove a mesh screen to shorten it.
Only 1.5 inches across, this grinder is an inexpensive and downright tiny means of readying cannabis bud to smoke. It’s not what we’d call “heavy-duty,” but it’s a decent grinder to have for traveling, in addition to a sturdier grinder for regular, at-home use.
The Kingtop grinder is nearly as big as the palm of your hand, great for when you have a considerable amount of bud and don’t need to be discrete. Its four pieces include a magnetically sealed cap, a grinder, a mesh screen, and a catch tray—a big one, at that—and its 45 teeth ensure smooth grinding.
Mendo Mulcher makes some tough grinders—all out of solid, aircraft-grade aluminum—but this one might be the most useful. At only 1.75 inches across, it’s best for travel, and its extra-grippy construction ensures you won’t slip up while using it despite its small size. With only two pieces, you’re short a mesh filter. But it does have a cool, hardware quality to it.
This grinder has a lotta happy customers. Makes sense. It grinds weed evenly and with precision, it’s built like a tank, it has a mesh screen and strong magnetic seal, and it hovers around 20 bucks. It’s a workhorse, built from materials that’ll keep it gliding through many a grind.
For a more tactile option, get Aerospaced’s grinder. The hand crank operates a set of blades, which chop up weed and filter it through a mesh screen. The clear lid allows you to monitor the entire operation.
If you’d call your personal style minimalist and refined, then here’s a grinder to match it. Made from aluminum alloy and unmarked with labels and logos, it is an accessory worthy of a high-class vape and top-grade flower.
Magic Flight’s grinder is part of its wooden Launch Box vape kit, fitting snugly over the opening of the vape so you can transfer freshly ground bud without a mess. If you’re looking for a beautifully carved, non-aluminum grinder (the grate is made from stainless steel) that’s part of a matched set—hell of a flex, right?—opt for this.
Phoenician medical-grade grinders get you a medium sheer on your weed—not too fine or too chunky. But more importantly, their grippy sides and deep bowls are intended to help users with arthritis (or folks with clumsy hands).
The Tectonic9 leans to the Inspector Gadget side of things. You put the weed into the chamber and grind it up, standard procedure. But accessing it is what is pretty damn nifty: That silver dispenser flips up from underneath the grinder and fits over a hole (which you manually open and close). Tip, and freshly ground herb neatly falls out.
The Pillar wasn’t built to be shoved in a junk drawer or lost under the couch. It glimmers, it is gold. Or rather, brushed brass. It’s a statement grinder if we’ve ever seen one. Besides aluminum grinding teeth and a scraper, the catch compartment is impressively spacious.
You get into spoil-yourself territory with the Santa Cruz Schredder. Known for its unique tooth design, it churns out perfectly ground, fluffy weed into a canister sealed with extra-strong magnets. You buy it once, then never have to worry about buying a grinder again.
Kannastör’s grinder is a mix-and-match marvel with extra storage options, two removable screens, and the option to break it down into a more portable size. Better yet, it comes with two interchangeable graters (hence the name) plates so you can pick your coarseness—fine or medium. Made with hardened aluminum in a matte design that looks real nice, it’ll last you.
Instead of aluminum or zinc alloy like most cheaper grinders, Iaso’s grinder is constructed out of stainless steel. That means the canister and its teeth will stay strong. Iaso also uses a special labyrinth seal design intended to prevent annoying binding or sticking. It’s a luxe option for sure.
Here’s where things get wild: an electric grinder. Eliminate user error altogether. The Otto automatically adjusts to the herb, sensing exactly what grind is required for the best results. Then, it funnels what it grinds directly into a paper cone for easy rolling (you can skip this step). Of course, then you’re stuck with machine error—charging, storage, maintenance, all that. Nevertheless, it’s a cool toy.
These 15 best weed grinders—most of them with four pieces to grind marijuana bud, sift pollen, and store the results—are available online and fit any budget.
What’s the best cannabis grinder?
In order to smoke or process our buds, it’s usually necessary to break up the buds first, especially if they’re really dense!
Most growers chop or grind their marijuana buds so they are easier to use!
When smoking, grinding help your buds go further by “aerating” the buds (make them fluffy) so they burn more efficiently. This is can make buds feel stronger and last longer compared to breaking it up with your fingers!
Dense buds like this are extremely difficult to break up properly with your fingers
Most common tools for grinding or chopping cannabis:
- Hands/fingers – just okay
- Scissors – a little better than using your hands
- Grinders from Around the House – tools that are meant to grind herbs, coffee and tobacco all do a pretty good job with cannabis, too. However, these usually don’t have any way to catch kief that falls off your buds.
- Specially Made Cannabis Grinders – these can go from terrible to great, depending on the model!
There are a millions ways to chop up your cannabis, and many work well, but if you are serious about getting the most from your buds, there’s a style of grinder that rules them all.
Grinders that are made for marijuana come in many different colors and models….
But which grinder works the best for weed?
4-Piece Cosmic Case – The Best Cannabis Grinder!
Important Note: Unfortunately, production of the Cosmic grinder seems to have halted. We’re devastated by the loss of this first-rate grinder, but we’re currently testing dozens(!) to find the next best thing. For now, we’re using our old Cosmic grinders and the Santa Cruz Shredder, which has been a good backup. If you have a grinder for us to try, let us know here!
I’ve used dozens of grinders over the years, and some are definitely better than others! Many of them can be a really great choice, but there’s one to rule them all.
Now-a-days, I will only use a 4-piece Cosmic Case grinder. It may not look like anything special (though they do come in various colors and sizes), but that’s not what makes it great. Its greatness lies in the fact that it is has been designed by cannabis connoisseurs from the bottom up.
First, let me warn you about the price… They’re realllllllly expensive. I’m talking up to $90 for their large models!
That may seem obscene, and it honestly is an obscene price for a grinder (which are normally closer to $15).
But if you grind up a lot of bud in your life, I think it’s worth it to invest in a Cosmic Case. I only got one because a guy at a head shop convinced me, but I’m glad he did because I’ve used them ever since.
About the Cosmic Case Grinder
It’s a sturdy piece of metal with good weight to it, and it has an overall very solid design.
The 4-piece “Large” version looks like this when you open it up.
Like all high-end grinders, it comes with a kief trap to collect all the kief/trichomes/glitter that naturally comes off your buds during the grinding process. That way you have kief for later!
Note: When a grinder is labeled as a “4-piece” grinder, the 4th piece is the kief trap (often called a “pollen trap” by sellers).
Kief/trichomes collect in the pollen trap so you can use it later!
It also has a very strong magnetic top that lets you easily open it up, yet the magnet is strong enough that it won’t fall off on its own even if you hold it upside down or keep it in a purse or backpack all day. This may seem like a small thing, but it’s a huge improvement over grinders with weak magnets (where the top comes off all the time) or screw-on tops (which get all gunked up after a while and won’t screw off easily anymore).
Those are great features that you should get from any high-quality grinder! However, the Cosmic Case has something else that makes it special….
What Makes It the Best Grinder?
The thing that makes this grinder so great is the weird holes it uses. They look like they’re going to let all your bud through in huge pieces because they’re so much larger than standard holes, but it doesn’t actually do that.
For whatever reason, these oddly shaped holes are just plain better (in my opinion) than the regular round ones. They shear the buds into a different consistency than normal grinders, and buds never get ground to dust.
The uniquely shaped holes shear your buds instead of grinding them into powder
The shearing makes any buds kind of fluffy, even if you’re using dense buds that are tough to break up.
I have found that buds actually seem stronger/more potent compared to not grinding them because the ground bud burns all the way through evenly in just one breath. This makes buds last longer since you use less at a time (though it can give you a head rush!).
The buds become fluffy due to the shearing action – this extra air makes buds burn better and they’ll often actually feel more potent!
It works great even with extremely dense buds!
Check out the 4-Piece Cosmic Case on Amazon!
When you use a great grinder like this, your buds will feel more potent and as a result your buds will last longer. Despite the cost, these are a good investment! It’s a top-notch present for a fellow enthusiast, or as a present to yourself, and I know you’ll become a believer as soon as you try one the first time!
