A handheld ultrasonic knife that vibrates a steel blade at 35 kHz to slice cured resin, PLA, wood, plastic, acrylic and PCB stock. Two speed settings and an electronic feedback loop that backs off on dense sections keep the motor cool, and reinforced internal cooling allows three to five minute continuous runs. It ships assembled with a mains cable and five spare blades. It suits hobbyists and small shops doing post-processing on 3D prints and circuit boards, where it competes with rotary tools and manual trimmers by cutting cleanly instead of grinding dust and burrs. The trade-offs are a corded body, short duty cycles and a blade that dulls on hard materials.

This handheld ultrasonic cutting knife vibrates its blade at 35 kHz to cut stiff materials. It handles cured resin, PLA, wood, plastic, acrylic and PCB parts. It is meant for cleaning up and trimming 3D-printed models and similar work.
Two speed knobs and built-in circuitry help keep the motor cool. Reinforced internal cooling supports three to five minutes of continuous running. The electronics lower the speed automatically on dense sections.
The grip is beige and made for detail work. The cutting action is friction-free, which protects delicate traces and thin-wall joints. It arrives fully assembled.
