The tool oscillates some 40,000 cycles per second, but the motion is so subtle that you reportedly can’t see or feel the vibrations. The action of the tool means it “breezes through an amazing array of materials,” according to MicroMark, who’s snapped up the North American distribution rights.
The demonstration looks good, but I wish they’d show close-ups of the cut quality:
MicroMark sells the Wondercutter S for $400.
