The Ripper, which launched this past 4/20, is available via the manufacturer’s website. A four-piece Ripper retails for $109, though it’s currently on sale for $99. If you’re looking to save a few bucks, consider the three-piece version (regularly $95, on sale for $80), which removes the middle chamber and kief screen. (Unpopular opinion: I don’t find kief catchers all that useful anyway.)
That doesn’t necessarily mean aluminum is the best choice, though. There are health issues to consider.
On the fence? I think you’ll get good use out of the Iaso grinder, but personally I’m more excited about version 2.0, which will hopefully see some kinks ironed out.
Grinding cannabis with the Ripper was a pleasure. Rotation is smooth, and it grinds flower to a consistent, fine texture. The 2-inch diameter is bit smaller than some mainstream grinders, but I found it worked fine for regular use and ends up saving some weight. If you grind a ton of cannabis all at once, you might want a bigger option.
Are there tradeoffs with stainless steel? Of course. It’s heavier and more expensive than aluminum. And because few manufacturers made grinders out of stainless steel, there are only a handful options to choose from. Luckily, that’s starting to change.
First, the plastic O-ring that fits between the lid and the rest of the grinder is unsecured and pops off almost every time I remove the lid. It’s not an essential piece, but it helps the grinder spin more smoothly, and it’s frustrating that a $130 grinder would have such a basic design flaw. The company assures me that the O-ring on the next version of the grinder will have a securely attached O-ring.
When I think about my kitchen, just about every metal utensil I use is made of stainless steel. The material is generally strong, long-lasting, and considered safe for food and other consumables. It’s also a breeze to clean up.
Where to Buy
From what I can tell, Iaso Goods might just be the first commercial manufacturer to deliver a 4-piece grinder made of stainless steel.

With only two pieces though, it doesn’t have a mesh filter.
