Cheap and dependable, this 5-piece budget grinder by iRainy is another great option for the cannabis user on a budget.

Weed Grinder Sizes

Weed grinders come in a variety of sizes, or to be more specific, pieces.

There is no best, or recommend size. What size weed grinder you buy really just comes down to personal preference, and should only be bought if it suits your requirements.

The most common sizes you’ll see are:

5-piece weed grinders can also be found, but are not commonly used or considered to be one of the more popular designs. But again, this is all personal preference.

If you need or prefer a 5-piece weed grinder, buy a 5-piece weed grinder. As long as the build quality and price meet your requirements, that’s all that matters.

Weed Grinder Build

Weed grinders are available in many different materials. Again, cannabis smokers will have their preferred type, but unless they’re made from very cheap materials. Most will work as they should, no matter what they’re made from.

Some common materials herb/weed grinders are made from are:

  • Wood
  • Titanium
  • Steel
  • Aluminum
  • Zinc Alloy
  • Plastic

Different Parts of a Weed Grinder

The different parts of your weed grinder will directly relate to what size weed grinder you decided to purchase. For instance, some budget 2-piece weed grinders will only have the lid, teeth/grinder section, and collection base.

Whereas your 4-piece grinder may incorporate a mesh screen, or sometimes 2 mesh screens, and a section to hold your bud, as well as the above. Many will also include extras, such as a pollen scraper.

If we presume it’s your 4-piece weed grinder with above-average build quality. The below will normally come as standard:

  • Magnetic lid (helps to secure your product)
  • Molded or engraved grip
  • Grinding section with sharp well placed diamond-shaped teeth
  • Mesh screen section, to collect/filter fine powders
  • Base section, that holds your weed crystals & pollen scraper

Before Deciding on the Best Weed Grinder

There are some important details to consider before making the decision on what weed grinder to buy.

Teeth: The number of teeth, and more importantly the placement of teeth should be a top priority when considering what weed grinder to buy. Cheap, badly made weed grinders are notorious for badly ripping and shredding weed. Never mind the headache of having to pick the weed out of the teeth when it becomes stuck, it’s pretty tedious.

Sections & Rims: Some weed grinders have a problem of weed build up on the rims. Which in turn can hinder if not completely stop the grinder from being able to turn. This problem can also appear on the lid of the grinder, especially if it’s threaded.

Of course, regular cleaning will help. But you know you have a cheap, badly made grinder when you’re having to pry open the different sections.

Capacity: Storage capacity is another important factor to consider. Your grinder may be the best grinder you’ve ever had in every other respect. But if it can only hold a small amount at a time, this can become a real annoyance if you’re a regular user.

Ease of Use: Your weed grinder should be easy to use, without all of the above problems. Essentially, it should be doing all the basics right and none of the bad. If not an enjoyable experience, it should at least be an easy one.

If you need to constantly struggle or go that extra bit just to have nicely ground bud, then your weed grinder probably needs replacing.

Affordability: Price is another factor when considering what weed grinder to buy. Is it a standalone weed grinder, or weed grinder kit? Will it be a 2-piece weed grinder or a 4-piece?

What about the build quality!?

These are all important factors to consider, that inevitably increase the price of the product. And like most things in life, the more premium products will always undoubtedly cost more.

But, that doesn’t always mean the most expensive is the best. There are some fantastic weed grinders out there at budget-friendly prices. So look about, you may just find yourself a bargain!
