The Ooze Hot Knife is an electric dab tool that makes handling any type of concentrate so much easier. The Hot Knife is a heated dab tool that prevents the extract from getting stuck to the tool and can make cutting off a small piece of a larger slab of concentrate a simple process. Screw the Hot Knife attachment onto a 510 thread battery (we recommend the Slim Twist) and press the button to heat up the ceramic knife tip.
