Pocket Grinders

Every grinder does the same job. What separates a Pocket Grinder from everything else is that it does it in a jacket pocket, a jeans pocket, a small bag pouch, or a rolling kit that travels with you every day. Pocket Grinders are built around a single design principle: the grinder should take up as little space as possible without giving up the ability to produce a clean, even grind on demand.

At 40–50mm in diameter, a Mini Pocket Grinder sits flat, adds almost no detectable weight, and handles exactly as much material as a single session needs, no more, no less. The collection centres on the Mini Pocket Magnetic Plastic Grinder 40mm in a 12-pack format, alongside the broader Pocket Grinder market from brands including Monkey King, Blazy Susan, Smoking Brand and the Magnetic No.1 family.

What Makes Pocket Grinders Different

Designed Around Your Pocket 

A standard 55–63mm grinder fits in a jacket pocket but creates a visible bulge. A Pocket Grinder at 40–50mm disappears into any pocket, jeans, jacket, or shirt without any outline. The reduced diameter is not just about being smaller; it is about being genuinely pocketable in the way that a standard grinder is not.

One Session, No More 

Mini Pocket Grinders handle enough material for one to two roll-ups per grind, which is exactly the right amount for most on-the-go sessions. You do not need a larger capacity when you are rolling at the pace you are using it. The compact chamber encourages exactly the right quantity per preparation without wasting material or grinding more than you need.

Lightweight Enough to Forget It Is There 

A 40mm Pocket Grinder typically weighs under 30g, close to nothing in a pocket or rolling kit. That is significantly lighter than a standard metal grinder at the same spec, and lighter still than a large sifter. For daily carry, weight matters, and Pocket Grinders are almost unnoticeable from a carry perspective.

The Stash Pot Format 

A stash pot grinder combines a 2-part or 3-part grinding function with a built-in storage compartment below, designed to carry pre-ground material separately from the grinding chamber. Unlike a standard 3-part catch chamber that collects material during grinding, the stash pot compartment is a dedicated storage space you fill intentionally before you go out. A practical variant for those who prefer to prepare in advance.

Available With Magnetic Closure 

The Pocket Magnetic Grinder format brings the rare-earth magnetic closure into a compact size. The Mini Pocket Magnetic Plastic Grinder 40mm at Local Supplies uses the same magnetic lid closure as full-size magnetic grinders. The lid clicks firmly shut and does not open in a pocket under normal carry conditions.

Metal and Plastic Both Available 

Small Pocket Grinders are available in both plastic and metal bodies in a compact size. Plastic pocket grinders are lighter and more colourful. Metal pocket grinders are more durable and maintain their teeth' sharpness longer. Both produce the same fine, even grind at the 40–50mm diameter; the material choice depends on whether you prioritise weight or longevity.

One of the Best Entry Points Into Grinding 

Pocket Grinders are consistently among the Best Sellers in the smoking accessories category. Their combination of low price, compact carry, and immediate practical value makes them the first grinder most hand-rollers buy and, for many, the format they stick with indefinitely.

Pocket Grinder Formats

2-Part Pocket Grinder 

A lid and grinding chamber in the simplest possible format in a compact size. Grind the material, open, tip out. No catch chamber, no storage below. Suits vapers who want the absolute minimum footprint, typically the flattest and lightest format available in the pocket-size range.

3-Part Pocket Grinder 

Adds a catch chamber below the teeth through which ground material falls during grinding. Most Monkey King pocket grinders use this format, where material is collected cleanly in the lower chamber without needing to tip the grinder. The same compact footprint as 2-part with practical material collection built in.

4-Part Mini Sifter Grinder 

The Blazy Susan Mini and selected compact metal grinders bring a fine mesh screen and kief collector into the pocket size. Rare in the 40mm format but available, the Blazy Susan Mini Herb Saver is a confirmed 4-part design at pocket scale. The smallest format that includes a kief collection chamber.

Stash Pot Grinder 

A unique format combining a grinder top with a dedicated storage compartment at the base designed to carry pre-ground material rather than just collect it during grinding. The Monkey King Stash Pot range is a confirmed example. Grind at home, store the prepared material in the stash pot, and carry it out. Practical for those who prefer to prepare in advance and carry ready-ground material for use on the go.

Pocket vs Standard vs Large: Size Difference in Practice

The practical carry difference between 40mm and 55mm is more significant than the numbers suggest. A 40mm Mini Grinder disappears into a pocket; a 55mm standard grinder creates a detectable presence. For daily on-the-go use, the compact format is the more practical choice even if the capacity per grind is smaller.

How To Use a Pocket Grinder

1. Pull the lid free; the magnet or friction fit releases with a firm, even pull.
2. Break material into small pieces and load the teeth chamber of a 40mm pocket grinder with a small, even amount for one or two roll-ups. Do not overload.
3. Replace the lid and hold the grinder firmly between thumb and forefinger. Rotate ten to fifteen times.
4. On 2-part models, open and tip directly. On 3-part models, remove the catch chamber to access the ground material below.
5. For a stash pot model, fill the storage compartment intentionally with pre-ground material before going out. Use the stash compartment to store and the grinder top to prepare as needed.
6. Clean with a small brush or cocktail stick; the compact size means residue builds up faster than in larger grinders. Regular cleaning keeps the teeth cutting cleanly.
