Dexso Dab Knife Review — 5 Amazing Dab Knife Features

This Dexso dab knife review covers the Black Leaf Dab Knife after one week of daily use — loading rosin, cleaning the blade, and running multiple heat cycles. The Black Leaf dab knife is an electric dab tool with a Dexso hot knife ceramic blade, USB-C charging, and 3 heat settings. Fordee from Herbistry420 was sent one by the Black Leaf team, then a buddy sent him a second — which says something about how it spreads through the community. Here’s the full breakdown.

Dexso Dab Knife Review: What Is It?

The dab knife — an electric heating tool designed to load concentrates into dab rigs, pipes, or e-rigs without the mess of traditional dab tools. The Dexso dab knife ceramic blade heats up on command, allowing rosin, wax, or other concentrates to slide cleanly off the blade directly into your device. The Black Leaf dab knife is compact, rechargeable via USB-C, and built for dab knife ease of use as its core selling point.

5 Amazing Features of the Dexso Dab Knife

1. Dexso dab knife ceramic blade. The Dexso hot knife ceramic blade is heat-safe, easy to wipe clean with a Q-tip, and heats evenly across its surface. Ceramic is a great material for dab tools because it doesn’t react with concentrates and is easy to maintain. The blade cap protects it when not in use — just pop it off to access the blade.
2. USB-C charging. The dab knife charges via USB-C at the base of the device. One note: charge it before first use, and remember you need to press the power button 5 times to turn it on (not 1 — this trips up first-time users, including Fordee).
3. Electric dab knife heat settings. The electric dab knife heat settings cycle through 4 modes: Blue (lowest), Green, Red, and White (hottest). You switch between electric dab knife heat settings by pressing the button 3 times. For most concentrates, the White (hottest) setting works well for clean loading with minimal residue left on the blade.
4. Dab knife ease of use. The dab knife ease of use is the main argument for this product. You pick up your concentrate cold, turn the device on (5 clicks), hold down the button to heat the blade, and the dab slides right off into your pipe or rig. No torch, no separate tool juggling, no sticky mess. The dab knife ease of use is especially appreciated when you’re already high and want a clean, simple loading experience.
5. Minimal waste. There is some minimal waste — a small amount of concentrate stays on the Dexso hot knife ceramic blade during the heat-and-drop process. But after a week of use, the reviewer considers it negligible. If you’re extremely waste-averse, it’s worth noting; for most users it’s a non-issue compared to the convenience gained.

How to Use the Black Leaf Dab Knife

Here’s the full sequence for using the Black Leaf dab knife:

1. Charge via USB-C before first use

3. Use the cold Dexso hot knife ceramic blade to pick up your concentrate
4. Hold the button to heat the blade — the dab slides off into your device
5. Use the button 3-click cycle to select electric dab knife heat settings (Blue → Green → Red → White)
6. Double-click to start a heat cycle on compatible devices
7. Clean the blade with a Q-tip while still warm after each session
8. Press 5 times to power off

Dexso Dab Knife Review Verdict

The Dexso hot knife review verdict after a week of daily use: it’s a solid, affordable dab tool that genuinely improves the loading process. It’s not a game-changing piece of technology, but it does exactly what it promises — the Black Leaf dab knife makes loading concentrates faster, cleaner, and more consistent than traditional metal tools. The dab knife ease of use alone makes it worth it at the price point. Black Leaf also makes a solid range of bongs, dab rigs, and accessories, so the Dexso fits well into their lineup.
