Grinders
The Grenade Grinder is a three-part metal herb grinder disguised as a miniature hand grenade — complete with a removable pin on top. It grinds, sifts, and stashes your herbs in one compact, discreet package that looks more like a desk ornament than smoking gear. We've had these on the shelf for years, and they're still one of the most fun conversation starters in the shop.
A novelty grinder that actually grinds properly is rarer than you'd think. Most shaped grinders sacrifice function for form — the teeth are dull, the chambers are shallow, the threading cross-strips after a week. The Grenade Grinder sits in a different category. The round body fits naturally in your palm, and the two halves twist apart to reveal sharp metal teeth that shred dried herb without the wrist strain you get from cheaper aluminium models.
The real trick is the 3-part design. Below the grinding chamber sits a pollen screen that filters the finest trichome particles into a separate collection compartment at the base. Over a few weeks of regular use, you'll accumulate a decent layer of kief down there — the most potent part of your herb, saved up for when you want it. The grenade body itself doubles as a stash container when it's closed. Toss it in a bag, leave it on a shelf — nobody's going to guess what's inside.
One honest limitation: the grinding chamber is compact. You're not loading a full evening's worth of herb in one go. It's built for a bowl or a single joint's worth at a time. That said, the small size is exactly what makes it pocketable. Trade-offs.
It's heavier than it looks — solid metal, not hollow plastic with a metallic coating. The textured surface of the grenade body gives you proper grip when you twist. The threading is smooth enough that it doesn't jam, though we'd recommend giving it a tap after grinding to knock loose herb down through the screen before unscrewing. The pin on top pulls out and slots back in; it's decorative, not functional for the grinding mechanism, but it completes the look and gives you something to fidget with.
Compared to a standard flat-top grinder of the same price, you're getting more personality and roughly the same grind consistency. If you want maximum throughput and a crank handle, look at something like a larger 4-part grinder. But if you want something that fits in a jacket pocket and makes people do a double-take, this is the one.

Complete your setup: pair the Grenade Grinder with a set of rolling papers and pre-rolled tips for a grab-and-go kit. If you're after a larger grinder for home use, check out our 4-part metal grinders with bigger chambers and deeper kief catchers.
Tearing herb apart by hand wastes trichomes — they stick to your fingers instead of ending up in your bowl or paper. A grinder with sharp teeth breaks the material down evenly, which means it burns more consistently and you use less per session. We've seen customers cut their herb consumption by roughly 15-20% just by switching from hand-breaking to a decent grinder. That adds up fast.
The pollen screen takes it a step further. Without one, those fine trichome particles just mix into the ground herb and get burned immediately. With a screen, they collect over time. After 2-3 weeks of regular use, you can scrape out the kief compartment and top a bowl with it — noticeably more potent than the herb alone. It's essentially free bonus material that you'd otherwise lose.
And the stash function? Underrated. A grinder that doubles as a sealed container means one less thing to carry. The metal body blocks light and keeps contents reasonably airtight. Not as good as a dedicated glass jar for long-term storage, but for a day out, it does the job.
The Grenade Grinder comes in several colour and finish variations. When you order, the warehouse picks one at random — you might get matte black, olive green, silver, or another variant. If you order more than one, the team will do their best to send you different designs, but they can't guarantee it. If you're collecting the set, ordering 2-3 at once gives you the best odds of variety.
Medium-fine. The metal teeth produce a consistency that works well for rolling and packing bowls. It won't give you a powder-fine grind like a dedicated vaporiser grinder, but for combustion use it's spot on.
No — designs are selected randomly by the warehouse. If you order multiple units, the team tries to send different designs, but specific colour requests aren't possible.
Use a stiff-bristled brush (a clean toothbrush works) to sweep both sides of the screen. For a deep clean, soak the screen section in isopropyl alcohol for 20 minutes, then rinse with warm water and let it dry completely before reassembling.
Purely decorative. It pulls out and slots back in for the look, but it doesn't affect the grinding mechanism. It does make the disguise more convincing, though.
Enough for one joint or one bowl per load — roughly 0.5-0.8g of dried herb. It's a pocket grinder, not a bulk processor. For larger sessions, you'll grind in two batches.
The metal body contains odour better than plastic grinders, but it's not fully airtight. Fresh, pungent herb will still be faintly detectable at close range. For complete odour control, transfer ground material to a sealed glass jar.
Metal teeth hold their edge far longer than plastic or acrylic alternatives. With regular cleaning to prevent resin buildup, you'll get months of consistent grinding before noticing any difference.
