Best Of The Rest 



What is the best grinder for Kief?

What the devil is Kief?! If you have to ask yourself this question, you’re not smoking right. Finding a nice 4-piece grinder is crucial if you want to ensure your kief and buds remain separate. Kief is the small crystals called trichomes that cover the cannabis buds, and more specifically it is a collection of these trichomes. They’re highly-prized amongst the cannabis community, as they taste better and smoke stronger. This is why we recommend a 4-piece grinder because kief is such an amazing thing to smoke. If you don’t know how to use kief, then we’ve got a guide on how to smoke kief here:

  1. There are a few ways to smoke kief, firstly you should allow it to collect for a few days or weeks or even months, at the bottom of your grinder. 

  2. Then you need to make a decision on how you want to smoke it, the best ways to smoke kief are; sprinkling it across a joint, putting some in the top of a bong hit, putting some in with a vaporizer, or if you have enough smoking a kief vape, mixing it in with something to make edibles. 

  3. If you want to make edibles with kief, you will have to have a vaporizer. That is because it’s too difficult to decarboxylate kief normally. 

Finding the right Kief catcher will set you up for a sweet smoke, trust me if I had the best Kief Catcher in the market, I'd be making my very own bubble hash! Check out the list below for more exciting 4-piece grinders.

Does Walmart sell herb grinders?

Yes, Walmart has many ‘herb grinders’ that we found. The ‘Titanium Herb and Spice Grinder, Mini (5-Piece)’ as one example, and also more comical grinders such as the ‘3 piece Pokemon Pikachu and Pokeball themed herb grinder spice crusher (Pokeball). From Stainless steel to anodized aluminum, zinc alloy to basic plastic grinders, Walmart has everything! Who’d have known that the biggest supermarket in the world had such great taste in hobbies? 

We wouldn’t really recommend buying one from Walmart, however. They’re definitely not considered experts in the ground field, and although it’s nice to get a grinder in person sometimes, we would only recommend buying one if you don’t want to buy one online for whatever reason. 

How to use a grinder

Now, we’re not here to patronize anyone, but we understand that not everyone is a full-blown stoner. We want to make sure that everyone has all of the information they need, and we, therefore, have this guide for how to use a 4-part grinder:

  1. Take about 0.1 grams of weed, preferably a bud, but if your grinder isn’t very good (hence why you’re on this article in the first place!) then break it up into smaller parts, and then add it to the grinder. Take all stems out of it. You don’t want to grind stems.

  2. Close the top of the grinder onto the rest of it, and turn it a few times left and right.

  3. Open the top of the grinder with it facing upwards, take any parts of weed that haven’t ground out, or wiggle them around and put them back in and grind again.

  4. Turn the middle of the grinder and hit the ground up weed onto a rolling table, or simply use the grinder as storage for it if you don’t want to use it all in one joint. 

  5. If there is any weed left, you can take something and push it over the mesh and collect more kief.

If you’re still confused, then take a look at this video. This grinder is actually the Official Potter grinder, which we have listed as our number 8 grinder on this list.
