Our best-selling Stainless Steel 1.75” 4-piece herb grinder is ideal for those who enjoy smaller doses, plus the convenience of taking your medicine on the go! 

The weight and feel of this small herb grinder is durable and heavy duty. Unlike aluminum grinders, it is constructed of 100% medical grade stainless steel, making it ideal for medical patients and anyone who has health concerns using aluminum products. 

This small grinder with a kief catcher is built with the same design methods and technology used in aerospace and renewable energy fields. It is high quality, guaranteed to perform and last a lifetime.

This 4 piece grinder features our Patent Pending labyrinth seal design. With our exclusive labyrinth seal solution, the top and middle pieces of the grinder are specially sealed together so your herb stays securely inside – no spills and no lost herb to worry about.

Create the perfect grind with just a few turns of the grinder. Sharp diamond-shaped teeth will cut and grind your herb with ease, and knurled top and bottom pieces save you from excessive wrist strain.

This four piece grinder includes a kief catcher or pollen catcher that functions as a storage compartment for collecting kief.


A kief screen is a type of sift screen used to separate ground herbs from kief. An ultra fine stainless steel mesh screen allows the trichomes to pass through to the bottom chamber, while the bigger herb pieces remain in the catch chamber.

Our 4 piece grinder with a kief catcher features a sift screen and catch chamber on the bottom to collect those potent trichomes that fall off during the grinding process. The stainless steel sift screens are removable, allowing you to choose between fine and medium micron sizes. 

You can sprinkle these trichomes on top of a bowl, in a joint, or use it in cooking and baking your favorite meals and treats! 

The bottom chamber may double as a stash container for ready-to-go ground flower. Elevate your experience by upgrading to the best small 4 chamber grinder!

    Amazing build quality!

    Published by Fox on Oct 8th 2021

    This might be the best grinder I've ever come across - considering I have a space case in my collection to compare it with. The build quality of this piece is simply stunning! Thanks for the fast shipping.

    Published by Susan Coté on Aug 31st 2021

    I absolutely adore how fluid this grinder's action is. It gives me the prefect grind with minimal effort, it's a great size, and it just feels so study and solid in my hands, which I absolutely love.

    Extra Satisfied

    Published by Trevor Allen on Feb 20th 2021

    Top to bottom, I've been blown away by IASO. Unreal customer service and swoon over this grinder. It's extra satisfying to use—buttery smooth, gliding with precision. There are a few qualms about how small this is—I think it's the perfect size, for so many reasons: it grinds the perfect amount for a single session (it feels like you are brewing some sort of artisanal small lot pourover); it stores easily, almost anywhere; the machining, weight and size make it feel like some sort of sexy spy gadget (people will ask me what it is whilst I'm milling with it). Point is, this thing is far superior to any grinder I've ever used. I highly recommend it. If you want a bigger grinder, get their bigger grinder. You'll never think about the price tag again—you'll be too distracted by how enjoyable it is to use.

    Iaso Small Grinder

    Published by Hilary on Jan 13th 2021

    This grinder far exceeded my expectations. I was looking for a small, high quality grinder and I found this one mentioned in a “top 10 of grinders” on the web. I thought I’d give it a try and I’m not disappointed. It had the look and feel of exceptional quality, it grinds like a dream, effortlessly. The small touches like the angled storage section and the curved crystal catcher make it unique. It’s perfect for my handbag or pocket although it’s fairly weighty but that adds to its beauty. I don’t often write reviews but I am so pleased with it I thought I’d share my findings. I am in the U.K. and it came reasonably quickly considering it was coming up to Christmas and during the Covid lockdown.

    Yes it’s expensive, but seriously good investment! When you hold the product, the price makes sense, exceptionally well made and performs flawlessly. Plus you’re only gonna need to buy it once as it will last a lifetime. Have recommended to all my friends.
