This video shows the comparison of 28k ultrasonic food cutting machine and traditional cutter.

Ultrasonic food cutting machine is the use of wave energy for cutting a class of equipment, its biggest feature is the cutting without cutting edge. The traditional cutting is the use of cutting tools with sharp edges, pressed to the cutting material. This pressure is concentrated in the edge, the pressure is very large. More than the shear strength of the material being cut, the material of the molecular combination was opened, it was cut off. As the material is a strong pressure to pull hard, so the cutting knife its edge should be very sharp, the material itself to bear the relatively large pressure. Its soft, flexible material cutting effect is not good, more difficult to sticky material.
