NEW! Three Piece Stainless Steel Grinder 2.5"

Best grinder I have ever had. I have had many other the get dull and just don’t last. IASO has the best quality and most durable grinders. I wish there was a bigger chamber so it could also be used as a storage with grinder. I have ordered many products from them. Very pleased and excellent quality.

Honestly ill never end up buying anything from this conpany again! This is the best grinder i have ever used and will probably last me the rest of my life. Iaso makes awesome products that will last longer then you. Thanks for doing what you guys do.

We're trying to buy sustainable items that will last a lifetime, and this fits the bill. It is beautifully machined and very fun to use. My husband is thrilled with his gift.

The fit and finish are exemplary. Machining is all very clean, and the brushing is very well done. The grip on the lid is very nice compared to most knurling. The lack of chamfer at the bottom of the grip makes the right angle cut a bit sharp, so watch out for that. All threads are smooth and easy to turn, but also feel like they lock in position. The magnet is strong, but the grinder is still very easy to turn. The deep blades are sharp and cut through material effortlessly. When the grinder is upright, material grind to a medium coarseness. With the 3-piece, you can invert the grinder and make several additional turns to get a very nice, fluffy grind. I like to clean it by filling the lid with isopropyl, "grinding" that while it's inverted, then flipping it and grinding a little more. Then running under water, and it's like brand new.

This is a great product. It came as a four piece, I use it as a three piece taking out the screen section. It's easy to fill, grind, and dispense. The grind is fluffy making it burn nicely. The design reduces the work for my troubled hands, I am thankful for that. Would absolutely recommend this grinder.

The ultimate grinder!!! I've tried every "high end" grinder out there, including other stainless steel brands. This Iaso grinder is hands down, the best quality grinder I've tried. The machining on this piece is top quality. Pieces all fit together super easy, no finicky threads. I've only put about 2 ounces through it so far, but it has performed flawlessly. All my other grinders ended up with threads that got stuck, or would stick. With this design, those issues are gone. This grinder is a tank. It does its job well, and its built to last.

Very well made. Ordered the 3 piece but got the 4 piece. That’s ok, you can just take one piece out and you have a 3 piece and in case I want to start saving my kief again, I’ll just change it back to the 4 piece. Last grinder I will have to buy. Beautiful.

Choice of material (alloys) matters, and this Stainless Steel Grinder trumps any anodized aluminum out there. Most notable differences: lack of sticking or needing to clean; typical grinders start sticking after 15 to 20 grams worth of use and tend to get worse over time leading to jams. One of the easiest grinders to turn as you work through plant material. The Kief catcher is perfect for using most with every grind while maintaining a crust that can be scraped down whenever you want a little more. The output of the grind could be better (i.e. does not rate the highest for breaking up small hard buds) as a future enhancement, but hands down this is the grinder I would buy if I smoked daily or wanted that unique piece that no shop has.

Best grinder I've ever used. Smooth operation, easy cleaning. Awesome product!

I love the weight and size of this grinder. Also, its very sharp teeth do their job quickly and efficiently.
