Handheld Ultrasonic Cutting Knife 35 kHz / 40 kHz
Manual cutting with sealed edges – 35 kHz and 40 kHz, long-blade option, paired with the 2000B / 2000BL / H20-B handheld generators.

Scissors force, knife would not dare
The handheld knife vibrates its edge at 35–40 kHz — the operator guides, the blade does the cutting. Hand force drops to a guide pressure, and on synthetics the edge seals as it cuts: webbing ends, ribbons and trim come off finished.
Two handles (gun and straight) and two generators (2000B / 2000BL, H20-B) make up kits for every shift — from a trim bench to field service.





Choose the set that fits the hand and the job
| Kit | Handle | Generator | Blade | Best for |
|---|---|---|---|---|
| Gun kit 35 kHz | Gun type | 2000B / H20-B | Standard | Trim benches, packaging lines |
| Straight kit 35 kHz | Straight | 2000B / H20-B | Standard | Precision guiding along templates |
| Long-blade kit 40 kHz | Gun type | 2000BL (800 W) | Long blade | Deep cuts, webbing rolls |
| Pen cutter | Pen | Compact generator | Fine tip | Detail work, prototypes |
All kits share the tool slot system — blades and welding tips swap without retuning the generator.
What operators notice first
Low hand force
The blade cuts; the hand only guides — less fatigue over a shift.
Sealed edges
Synthetic webbing and fabric do not fray after the cut.
No residue
No melted burr to trim off afterwards.
Two handle types
Gun for grip, straight for precision — same platform.
Swappable tips
Cutting blades and welding tips share the slot.
Protective generator
Tool overload protection with alarm auto-reset.
Technical specification
Kits ship as a working set: handle, generator, blade, spare tip and case.
Choosing a kit
Send material samples or describe the cuts.
We cut-test and recommend handle + blade.
Kit ships with the test-cut samples.
The same platform welds — add a welding tip and the kit becomes a handheld spot welder.

FAQ
40 kHz or 35 kHz?
Both cut similarly on thin synthetics; 40 kHz suits finer work, 35 kHz handles a wider material range.
Can it also weld?
Yes — swap in a welding tip; the 2000B generator supports both operations.
Blade wear?
Blades are consumables — stock spares; custom geometries are available.
Is there a cordless version?
The current line is mains-powered; discuss field needs with us — solutions exist.
