How do you charge the Puffco Hot Knife?
Plug it in with a USB-C cable. Puffco says it charges from empty to full in about 25 minutes, and you can triple-click the button at any time to check the level.
- Use a standard USB-C cable and a computer port or phone charger.
- Charge on a hard, dry surface.
- Unplug once it is full rather than leaving it on the charger for days.
How do you care for the Hot Knife tip?
Wipe the tip after use while it is warm and keep the cap on between sessions. Puffco does not publish a separate tip cleaning routine, so a gentle wipe is the safe approach.
- Wipe the warm tip with a cotton swab or paper towel.
- Avoid scraping it on metal or glass, which can chip the glaze.
- Replace the cap to protect the tip in a pocket or bag.
- Do not submerge the Hot Knife in water or alcohol.
Can you replace the Hot Knife tip?
Puffco does not list a separate replacement tip for the Hot Knife on its product page, and the tool is covered by a 2-year warranty against defects. If your tip chips, contact Puffco support about warranty options.
If replaceable tips matter to you, some other heated tools sell tips separately. Browse our dab accessories to compare loading tools.

What does the Hot Knife replace?
It replaces a standard cold dab tool. A cold tool lets sticky concentrate cling to the metal, while a warm tip releases it cleanly so less is wasted.
Puffco pairs the Hot Knife with the Peak, Peak Pro, Proxy and Pivot, but it works with any chamber or banger. If you use a Puffco New Peak, it makes loading the 3D Chamber much tidier.
Is a heated loading tool worth it?
Yes, if you load sticky concentrates often. A heated tip lets concentrate release cleanly, so less is left behind on the tool and more ends up in your chamber or banger.
A cold dab tool works, but sticky textures tend to string and cling. You end up scraping, wiping or reheating, and some of each load is wasted. Over weeks of use, that small loss adds up. A heated tool also makes it easier to place a load exactly where you want it, which matters in small chambers like the one in the Puffco Peak Pro. If you mostly use firm, easy-to-handle textures, a standard dab tool may be all you need.
What mistakes should you avoid with the Hot Knife?
The most common mistakes are holding the tip against concentrate too long, touching the hot tip and capping it before it cools.
- Overheating the load: you only need the tip warm enough to release concentrate. Release the button once it is placed.
- Touching the tip: the ceramic gets hot. Hold the body only.
- Capping too soon: let the tip cool briefly before you put the cap back on.
- Scrubbing with metal: wipe the tip with a cotton swab instead, so you do not scratch the glaze.
- Running it flat: triple-click to check the battery before a session so it does not die mid-load.

Frequently asked questions
Is a Puffco Hot Knife worth it?
If you load sticky concentrates often, many people find it worth it. The warm, glazed ceramic tip releases concentrate cleanly, so less sticks to the tool and more ends up in your chamber. It charges in about 25 minutes and fits in a pocket with its cap on, which makes it handy at home or on the go.
Is a Hot Knife needed for a Puffco?
No. Every Puffco device works with a standard loading tool, and Puffco includes one with its devices. The Hot Knife is an optional upgrade that makes loading cleaner and faster, especially with sticky concentrates. It also works with other chambers and bangers, not only Puffco.
How long does the Puffco Hot Knife take to charge?
Puffco says the new Hot Knife charges from empty to full in about 25 minutes over USB-C. You can triple-click the button at any time to check the battery level. Charge it on a hard surface with a standard USB-C cable and unplug it once it is full.
How do you check the battery on a Puffco Hot Knife?
Press the button three times quickly. The Hot Knife shows its battery level so you know whether to charge it before your session. This triple-click battery check is one of the updates on the new Hot Knife compared with the original model.
What is different about the new Puffco Hot Knife?
Puffco lists sturdier construction, a three-click battery level indicator, a rounded glazed ceramic tip, an updated button design and a secure cap with a lanyard loop. The glazed tip is designed to leave more concentrate in your chamber and is temp-tuned to protect terpenes.
