Stainless steel is much harder than aluminum and is often considered a better option for herb grinders. Aluminum grinders usually show signs of dulling teeth and other wear and tear that Stainless Steel grinders don’t suffer from.
Vaporizer users are often more health-conscious with their cannabis consumption than smokers. That’s why we vape instead of smoke. We care about what goes into our lungs, and we also care about what goes into our herbs and how it’s handled along the way.

Why Avoid Aluminum Weed Grinders
Aluminum is soft and malleable. Over time, the teeth gradually become dull and lose their anodization. Some users have even found tiny aluminum flecks in their ground-up herb!
Santa Cruz Shredder after several years of use.
The best aluminum weed grinders are the Santa Cruz Shredder and Brilliant Cut Grinder. They both use the hardest aluminum alloys available, but they are known to dull and chip over time. Aluminum weed grinders will not last forever.
Stainless Steel is Much More Durable than Aluminum
The teeth in a Stainless Steel grinder won’t dull, dent, or chip over time as they do in an aluminum grinder. Stainless Steel is a much harder metal than the Aluminum alloys used in cheaper weed grinders.
The added durability of stainless steel applies to more than just the teeth. The threads and exterior body of stainless grinders will withstand much more abuse than any aluminum grinder can handle.
Because Stainless Steel is harder, it also requires different tools and machines to mill. This, along with the actual cost of Stainless Steel, is why stainless grinders are more expensive than soft aluminum grinders.
Recommended Stainless Steel Herb Grinders
Here’s a list of the best stainless steel grinders I’ve tested and reviewed. Stainless steel grinders aren’t mainstream enough to be found in smokeshops yet, so you must order these online.
Odin 4-Piece Stainless Steel Grinder
The Odin Grinder is a large, 2.5-inch-diameter grinder that is rather basic. It is a four-piece grinder that can also operate as a three-piece by removing the middle section.
The Odin Stainless Steel grinder is $99. Click Here to purchase.
It’s currently available in two different designs. The Odin grinder has basic Z-shaped teeth and round holes for the herb to fall through. The grind consistency is medium, which is perfect for most vaporizers and smokers, too.
The Odin Grinder is the most basic Stainless Steel grinder available. It’s simple and affordable with pretty standard features. It’s not a threadless grinder like many new weed grinders. The pieces still screw together using threads.
This grinder doesn’t spin, and it’s not all that joyous to use. It’s just a plain, decent stainless steel grinder.
The Odin can be used as a 3-piece or a 4-piece, allowing you to use the screen and build up a collection of kief, or keep it all together and have a more potent herb.
While I typically prefer a 3-piece, I find that the Odin functions better as a 4-piece. The Kief catch threads just aren’t as smooth as the main threads. Click Here to buy a Stainless Steel Odin.
Zam Stainless Steel Grinders
The ZAM Stainless Steel grinder is available in 3 different sizes: 1.8″, 2.1″, and 2.5″.
ZAM grinders are also a 4-piece design that can easily convert to a 3-piece.
The Original ZAM grinder is made out of Aluminum and is a tall and slender portable grinder. The Original ZAM is still available and considered a good grinder for pocket carry and usage with the Dynavap.
I’ll have a full review of the Zam Stainless Steel grinder soon. You can buy a ZAM Grinder in three different sizes, starting at $69 for the small and $129 for the large. Click Here to shop Zam Grinders
The Zam Stainless Steel grinders are popular and affordable. They offer 3 different sizes to accommodate your various weed grinder needs – a small one for travel and tuck-away usage, a large one for at-home users and daily smokers, and a medium one for those that can’t decide and want the best of both worlds.

Brilliant Cut Stainless Steel Grinder
The Brilliant Cut grinder is widely accepted as the absolute best weed grinder. The original Brilliant Cut was one of the first threadless grinders available and set the bar for all other herb grinders to chase.
The Original Brilliant Cut is made of Aluminum, but they recently released a premium Stainless Steel version of their luxurious grinder. The Stainless Steel Brilliant Cut offers the same buttery smooth operation as its anodized aluminum precursor, a completely threadless design, and a faceted exterior.
Nicest Grinder Available
Brilliant Cut Grinder is one of the nicest weed grinders available and is an absolute marvel to look at and a joy to hold and use.
Be Prepared to Wait.
The Brilliant Cut Grinder rarely goes on sale, and orders are often 3-6 weeks behind. However, good things come to those who wait, and the Brilliant Cut is well worth waiting for.
They’re made in Canada.

Herb Ripper Stainless Steel Grinder
The American-made Herb Ripper is one of the original Stainless Steel weed grinders. It’s undergone several major revisions over the years and continues to improve with each iteration.
In 2019, I helped the Herb Ripper test several finishes to determine which surface performs the best.
Testing and reviewing weed grinders is part of my job, and I’m always happy to help other passionate makers in the cannabis space.
The Herb Ripper is made in-house by a small family-owned operation. The designer is a cannabis user who set out to create a better weed grinder many years ago, and he’s still focused on improving.
The Herb Ripper uses high-quality stainless steel and has a thinner, sharper tooth design that produces a nice medium grind.
It’s a threaded grinder, but the threads are 1/4 “firemen” threads. It’s super quick to open and requires no excessive motion or energy.
The Herb Ripper is a 4-piece grinder. The included orange kief scraper is a badass triangular guitar pick with the R logo.

Spinny, Stainless Superiority: Old Mate Ball Bearing Grinder
This grinder has a functional ball bearing that holds its top piece. There’s no metal-on-metal contact around the teeth, and the top teeth float in perfect alignment with its free-spinning ball bearing.
The Aroma 3 grinder by Old Mate Designs is an Australian-made grinder with some cool features.
It’s a threadless design that opens with a gentle squeeze/pivot action to release the strong neodymium magnet. The 3-piece design is 100% stainless steel, and the teeth are incredibly sharp and capable.
My Aroma 3 grinder with PEEK bearings and nano-tech lubrication will spin for nearly 3 minutes.
Functional Ball Bearing
The Ball Bearing is fully functional, in addition to being ridiculously fun.
The top half spins freely on the center post while grinding. The teeth don’t touch any other metal surface.
Super Sharp Teeth
When the grinder is open, the top teeth are viciously exposed. They’re extremely sharp and make fast work of even the stickiest nugs.
When the top spins freely, your grind is ready.
The Grinder that DOMINATES My Reach Test
The Old Mate ball-bearing grinder quickly became a mainstay on my desk. It’s incredibly fun and satisfying to spin and play with, and it functions well as a grinder.
Its teeth are super sharp and grind up sticky nugs quickly and easily.
The threadless design is easy to open and close, and the magnets are strong without being obnoxious.
My only minor complaint is the OMD Aroma 3 can send bits of kief and herb flying from the centrifugal force if I spin the top too fast while grinding. It’s purely a ‘user error’ – but spinning the top freely is hard to resist.
It’s not a Gimick. It’s GREAT
Not only is this grinder sharp and durable stainless steel, it’s also incredibly fun and easy to use.
It’s amusing and pleasurable to grind and use. The free spinning top of this grinder is FUN and FUNCTIONAL.
The fidget-spinner element of this grinder is great. At first glance, I thought it would be gimmicky, but it has provided my ADHD brain with many benefits.
The Aroma 3 stainless steel grinder from Old Mate Designs will remain on my desk and serve as my primary grinder.

Which Stainless Steel Grinder is BEST?
These grinders are considered the best stainless steel grinders available and they are all high-quality and worth recommending. The best aluminum grinder is the Brilliant Cut, so it may seem natural that the Stainless Steel Brilliant Cut inherits the title in the stainless category.
The Brilliant Cut Stainless grinder with a polished finish delivers the nicest grinding experience out of all the stainless steel grinders, although the wait is long and they’re currently not even offering pre-ordering of the polished version. $135 for the matte version is asking a lot, considering the bottom is flat and it’s a matte finish and a LARGE Brilliant Cut (Aluminum) is only $110. I *really* like the Large Aluminum Brilliant cut and I’m bothered that the Stainless Steel version has a flat bottom instead of the signature gem cut pattern. The dual-sided faceted gem-cut is one of the characteristics that make the Brilliant Cut Grinder so special, but the stainless version only has the gem-cut pattern on the top half.
Both the Odin and ZAM stainless steel grinders are perfectly good high-quality grinders, just without any frills or fancy features. They’re affordable, but they’re not cheap.
After using the Odin for several months, I have absolutely zero complaints. It’s a perfectly good enough stainless steel grinder.
The Old Mate Designs Aroma 3 wins my reach test and I’m in love with it, but it’s not perfect and it’s not for everyone. The ball-bearing top is super fun and it’s a functional part of the grinder’s smooth interface, but it’s also susceptible to dirt and debris. After testing my grinder for several months, it still turns freely enough to be fun, but it’s nowhere near as fast and smooth as it was when it was new.
The Aroma 3 ball-bearing grinder also presents a few unique problems! The spinning top can fling kief and other small weedy particles if you spin the grinder too fast as you grind up your nugs. The fast-spinning top also makes the grinder more challenging to hold and carry than other grinders. The top turns very easily, and it’s caused at least a dozen drops as I’ve shared it with friends. The stainless steel shows no damage from any of the drops, though!

Thank you for doing the type of product reviews. I feel that these accessories are an important piece of gear you need, especially if you vape. cheers!!
Thank you for the excellent article. I own all three of the grinders you discuss, and agree with all your statements. All three grinders (my brilliant cut is the matt stainless version) are fabulous, but I was surprised that you did not mention stainless grinders by Iaso Goods in Burlington, VT. They are a small machine shop producing SS grinders in 1.75” and 2.5”. The Iaso grinders definitely deserve a place in a line-up of top quality SS grinders. Personally, I would rate them as equals in machining, design and function. They all have their own selling points, but all are lifetime grinders. I have no relationship with any of these brands, just an old guy who likes good machine work and good weed.
I would love to see the Pebble compared to these as well.
I love your reviews! I love my Stona too! It uses stainless steel plates, & I hoped to see it on your list as well.
It’s a non-traditional design and the handmade glass is breakable, so not the perfect grinder for every situation, but overall I love the whole experience of using it!
The Stona looks so damn sexy, i need one in my life for sure!
