The Vestratto Anvil stuffs desktop-level extraction into a 65 g stainless steel tube you can close your fist around. This butane-powered on-demand vaporizer uses a patented CopperCore thermal battery to absorb, store, and redistribute heat across every draw. You get the kind of dense, hard-hitting vapor usually reserved for plug-in rigs.
Vestratto is a Canadian company based in Mississauga, Ontario, and it holds a US patent on the CopperCore oven (US 11,399,574 B2). Where the DynaVap M7 prioritizes quick heat-and-go portability, the Anvil trades some of that speed for far greater thermal mass and vapor output. The result is a torch vape that can clear a full 0.1 g chamber in a single draw.
We scored it 8.7 overall, with 9.4 for vapor quality and 9.8 for build quality, which puts it #2 in our best butane vaporizers ranking behind the Tempest 2. Ease of use (7.5) is its weakest score, because torch aim and timing take practice. Value (7.8) reflects a $229 price that covers the vape, one oven and one bowl, with the torch, case and extra bowls on top.
What's in the Box
Vestratto moved the Anvil to an integrated stem design back in 2022, cutting down the part count. Current orders ship the body (mouthpiece and integrated stem) with a heat shield in your color choice. You pick a ThermoCore or DuraCore oven and a Half, Full or XL bowl. The Full Bowl holds about 0.1 g, while the Half and XL bowls are rated at 0.05 g and 0.2 g.
No carrying case, no torch lighter, and no cleaning tools. Setup guidance lives in Vestratto's online FAQ. Additional chambers, the magnet-equipped carrying case, and alternate heat shields are all sold separately.
At Vestratto, the Anvil costs $229 ($239 with the Silver Mist shield). Extra bowls are $35 each, the Anvil Utility Case is $42, and the Forge Version 2 induction heater is $369 before the Milwaukee M12 battery it needs. Vestratto sells the Anvil as a pre-order, doesn't accept returns, and treats orders with pre-order items as final sale.
65 g stainless steel body built like a tool
The body, mouthpiece and condenser are 316 stainless steel, plus a small titanium spiral filter. Colored heat shields are aluminum, and the Silver Mist shield is stainless steel. At 75 mm tall and 22 mm in diameter, the Anvil is barely larger than a thick marker and disappears in a closed hand.
Tolerances are surgical. Threads engage smoothly and every component mates with zero play. The modular design breaks down easily for cleaning, and the screens and O-rings are simple to replace as they wear.
For water use, Vestratto sells dedicated 14 mm and 18 mm adapters for your glass. If you already own custom stems, the 8 mm Universal Stem Adapter takes many third-party stems, though fit and heat handling vary by stem.
CopperCore heat storage and vapor quality
The CopperCore thermal battery is the Anvil's defining technology. A copper layer sits between the steel walls of the oven, soaking up energy from your torch and feeding it back to the chamber. The DuraCore version adds a protective steel band, while ThermoCore packs more copper for a bigger heat reservoir. No spinning required.
The Anvil uses hybrid heating with a strong convection bias. Thermal breaks limit conduction from the oven walls. Hot air drawn through the airflow ports does most of the work as it passes through the cannabis.
The CopperCore oven: copper rings between the steel layers, with an airflow slot above them.
After the click, the CopperCore keeps feeding stored heat back into the chamber, so you can take a slow, full draw without rushing or reheating. That sustained heat also makes passing it around genuinely practical.
Through glass, the Anvil produces vapor density that approaches what we get from desktop ball vapes. If you plan to run it through water (and you should), our guide to using vaporizers with bongs covers the setup. Native use works with the XL mouthpiece but gets noticeably harsh at higher extraction temperatures, which is why most experienced Anvil users gravitate toward glass.
How to heat the Vestratto Anvil: torch aim and timing
Snap discs give an audible click when the chamber is ready, and where you aim the torch decides how much heat sits behind that click. Aim at the top copper ring and you reach the click fastest. Aim lower, toward the thermal battery, and the heat-up runs longer but stores far more heat for a more intense extraction. If you're new to it, Vestratto suggests a slower 40-45 second heat cycle, since very fast heating can outrun the click and combust your bowl.
| Where you aim | Heat-up | What you get |
|---|---|---|
| Top copper ring | Fastest | Flavor-forward hits with lighter clouds, the spot for tasting individual terpenes |
| Middle section | Between the two | Thicker vapor and stronger effects, the everyday spot |
| Thermal battery (bottom) | Longest | Full extraction near combustion temperatures, dense hits that can clear the bowl in one draw |
Torch selection shapes your experience too. A single-flame lighter aimed at the top ring preserves the most flavor. A dual-flame torch heats faster and pushes extraction harder but burns through fuel quicker. Our temperature guide explains what lower and higher extraction brings out of your cannabis.
No battery needed: unlimited sessions on butane
The Anvil has no battery, no charging cable, and no power outlet dependency. Your fuel is a standard butane torch lighter, and your sessions are unlimited as long as you have butane to burn.
The trade-off is real: open-flame heating draws attention, and the steel body stays hot for a while after a session. Let it cool fully before it goes in your pocket. For home use, camping, or relaxed outdoor settings, this is a non-issue. For discreet public microdosing, an electronic portable is the better tool.
Loading, airflow and cleaning the Vestratto Anvil
Loading is straightforward: grind your cannabis, loosely fill the 0.1 g Full Bowl, and thread it into the body. The integrated stem simplified assembly, so loading takes under a minute.
On the current integrated stem revision, you adjust airflow by inserting a standard 1/8" hex key into the bottom of the chamber. Rotate the oven clockwise, even while it's hot. Practice it cold first, because turning the other way can unscrew the hot bowl. The airflow uses three round holes and three wider slots, with minimum flow exposing only the holes and maximum flow revealing both. That adjustable airflow lets you tune draw resistance to your preference.
Torch technique makes or breaks your results. Where you aim, what torch size you use, and when you stop heating at the click all affect extraction. This is both the Anvil's greatest strength (complete user control) and its barrier to entry (inconsistent sessions until you build muscle memory). We scored ease of use at 7.5, reflecting the skill investment required to unlock the Anvil's full potential.
Chamber choice is part of that learning curve too. The Half Bowl and Full Bowl each have an integrated screen, and swapping between them lets you match load size to the session you want.

Cleaning is simple once the Anvil has cooled. Separate the parts that come apart by hand and pull the O-rings so they stay out of the alcohol. Keep track of the small spiral filter too. Clean the metal parts with isopropyl alcohol, then rinse and dry everything fully before you reassemble or heat it. Leave the welded bowl base and the snap discs alone. Our cleaning guide covers the process in detail. Clean whenever residue starts choking the airflow or dulling the flavor.
A strong magnet is practically essential for handling hot chambers safely. The official case has one built in, designed to hold the hot bowl steady. Without it, unscrewing a freshly fired chamber is slow and uncomfortable. The good news: your AVB comes out evenly roasted when technique is dialed in, ranging from coffee-ground brown to dark chocolate depending on torch position.
Vestratto Anvil vs Tempest 2, DynaVap M7, HyperDyn and Tornado
Here's how the Anvil lines up against the torch vapes buyers most often weigh it against.
| Vaporizer | Our score | Heating | Weight | Bowl | US list price |
|---|---|---|---|---|---|
| Vestratto Anvil | 8.7 | Hybrid | 65 g | 0.1 g (Full Bowl) | $229 |
| Tempest 2 | 9.0 | Convection | 46 g | 0.15 g | $225 |
| DynaVap HyperDyn | 8.5 | Hybrid | 55 g | 0.25 g | $229 |
| Vestratto Tornado | 8.4 | Convection | 85 g | 0.3 g | $208 |
| DynaVap M7 | 8.4 | Hybrid | 33 g | 0.1 g | $89 |
| Vapman 2.0 | 8.1 | Hybrid | 50 g | 0.1 g | $199 |
Anvil vs DynaVap M7
The DynaVap M7 8.4 is the obvious cross-shop target. At $89 against the Anvil's $229 US list price, the M7 is slimmer (10 mm against 22 mm), about half the weight (33 g against 65 g), and works with compatible induction heaters. Our Anvil vs DynaVap M7 comparison lines up bowl size, heating routine and price side by side.
The Anvil's CopperCore changes the equation entirely. The M7 needs reheating sooner, while the Anvil's stored heat keeps each cycle going through a long, slow draw. Hits are denser, single-cycle extraction is more complete, and you never need to spin the vape during heating. Choose the M7 for speed, pocket-friendliness, and value. Choose the Anvil for denser hits and a longer draw window. For a closer power matchup, compare the Anvil and HyperDyn.

Anvil vs Vapman 2.0
The Vapman 2.0 8.1 is another handcrafted torch vape built for enthusiasts. Made in Italy by INHALE with a wood-and-metal body, it focuses on small, flavor-rich hybrid doses with an artistic design philosophy.
The Anvil produces vastly more vapor per cycle and hits harder across its entire temperature range. The Vapman counters with a gentler, more contemplative session style and a lighter body. Both are repairable, battery-free artisan tools. Choose the Vapman for gentle sipping, the Anvil for full-throttle one-hit extraction. Our Anvil vs Vapman 2.0 comparison has the details.
Anvil vs Tempest 2
The Tempest 2 9.0 represents the newer wave of portable ball vapes. It uses heated balls for convection-heavy extraction, a fundamentally different approach to desktop-level power in a pocket format. The Tempest 2 stands far taller (122 mm against 75 mm) but weighs less (46 g against 65 g).
The Tempest 2 (right) stands far taller than the Anvil but weighs 19 g less.
Both deliver massive vapor from pocket-sized bodies through different mechanisms. The Tempest 2 leans on convection through its ball system. The Anvil's CopperCore provides hybrid heating with longer sustained heat per cycle, which makes it better for sharing. On our scores the Tempest 2 is the stronger all-rounder, 9.0 against 8.7, for $4 less at US list price, which is why it sits one place above the Anvil in our best butane vaporizers ranking. Pick the Tempest 2 for its visual heat gauge and cleaner flavor. Pick the Anvil for a shorter body and a draw window long enough to pass around. Our Anvil vs Tempest 2 comparison goes deeper.
Is the Vestratto Anvil worth it?
For the right buyer, yes. Bong veterans transitioning to vapor who refuse to compromise on hit density get exactly that. Run through a 14 mm water piece, the Anvil delivers the kind of thick clouds you're used to from a bong.
Home-session ritualists who want a compact vape with no batteries to degrade and no firmware to update. Upkeep comes down to swapping screens and O-rings as they wear.
Technique-driven users who enjoy dialing in extraction with manual temperature control. If you treat your sessions as a craft, the Anvil rewards every adjustment you make.
Skip it if:
- You want quick, low-key hits away from home. The open flame draws attention, and the body stays hot after a session.
- You don't want to learn torch technique. Aim and timing decide every session.
- You want the easiest butane vape to repeat. The Tempest 2's visual heat gauge made our favorite level easier to hit again, and it scores 9.0.
- You want to spend under $100. The DynaVap M7 costs $89.
- You want the option to send it back. Vestratto doesn't accept returns, and pre-orders are final sale.
Final Verdict
The Vestratto Anvil delivers on its core promise: desktop-level extraction from a 65 g stainless steel package. The CopperCore thermal battery, modular chamber system, and adjustable airflow make it one of the hardest-hitting torch vapes we have tested. Its larger sibling, the Vestratto Tornado 8.4 , produced even denser vapor in our sessions. If you're weighing the two, our Anvil vs Vestratto Tornado comparison sets out the bowl size and handling differences. Sparse included accessories and a genuine learning curve are the costs of entry. For anyone who puts raw vapor performance above all else, the Anvil earns its #2 place on our best butane vaporizers ranking.
