A metal grinder is often seen as the most reliable but there are varying types of metal used in grinder production, each offering different results.

a. Titanium Grinder

The titanium grinder is prized for having the sharpest teeth. Even the most tenacious of nugs is reduced to grain as fine as sand in the razor-lined chamber of a titanium weed grinder. Even after repeated, heavy use, it’s difficult to dull titanium teeth. You can also count on your titanium grinder to be surprisingly light since it’s not as dense as it may appear.

Since they’re highly portable, they’re perfect for the smoker on the go. Though titanium grinders themselves aren’t hefty, their price tags can be another story.

b. Aluminum Grinder

Much more common and affordable than titanium grinder models, the aluminum grinder requires a bit of scrutiny at your point of purchase. That’s because aluminum comes in a wide range of grades. A cheap aluminum grinder could potentially leave aluminum shavings in your herb while a high-grade aluminum grinder could hold up alongside the best titanium weed grinders if properly maintained.

Since aluminum quality can vary, it pays to try and determine the quality of the aluminum used in the creation of a weed grinder. Look for high-grade aluminum, such as anodized aluminum. While aluminum is one of the most hygienic metals, some aluminum grinder models actually employ the use of medical-grade stainless steel teeth for longevity.

However, aluminum is a very easy metal to clean so regular maintenance of an aluminum herb grinder is a breeze. Aluminum varieties tend to be rugged options so they’re perfect for travel. They’re also pretty easy to find if you need a decent herb grinder in a pinch.
