What Material Is Safe For a Grinder?

There is no straight answer to this question. Confusion is all over, and our information, if not consumed consistently, could add to the confusion.

Let's break down herb grinders materials:

We wrote about titanium as the ultimate material for grinders, but that doesn't mean that the grinder will be the most durable, as it's mechanical construction is important as well.

So, what about stainless steel? Well, it really depends on its grade. A 304 stainless steel grinder might be better than any low-grade Asia-made stainless steel, but the recommended grade would be 316L. So, does that mean that a grinder made from 316L stainless steel is safe? Not really, because poor construction of the grinder will develop friction and wearing down will occur.

Grinder Construction? Friction - Friction - Friction

Yes, three times is the magic number. Why? Because we wish to emphasize the importance of a very simple rule: friction. Friction is generated by the contact of two surfaces. Accelerated friction is generated when the materials are made from the same compound. So, it doesn't really matter what material the grinder is made of—as long as the contact surface consists of the same compounds, the grinder will degrade. Naturally lower grade materials or softer materials tend to wear out faster. A high-strength material will do a better job withstanding the friction.

If your grinder is made from low bio-compatible material, it most probably is made from the same materials that put you in direct risk of medicinal contamination.


To sum it up, a safe grinder’s durability depends on both materials and construction. The minimum requirement is a biocompatible material. For longevity, a well-thought construction is required. With MMJGRIND, we have adopted both!
