With a blade that oscillates over 40,000 times per second—faster than you can see or feel—these knives make fast, clean, and precise cuts in a variety of material. Use them to remove supports from 3D printed objects, shape printed circuit boards, and sculpt custom spacers, gaskets, and parts of all kinds.

These knives are faster than manual precision-blade knives and scalpels. Unlike hot-blade knives, they do not require a heat source and won't melt, burn, or crack your material. They're also less costly and easier to set up than laser cutters.

A contoured handle makes these knives easy to hold as you apply pressure. They include a pack of 40 replacement blades.

To turn on knives with a momentary switch, press and hold the button on the handle. For safety, these knives turn off when you let go of the button. They come with a rechargeable battery, so you can bring them anywhere you need.

Knives with a maintained switch stay activated when you press the button. Press again to turn them off. They help prevent hand fatigue when cutting for extended periods, since you don't have to hold the button down. Select one of three speeds to suit the thickness and hardness of the material you're cutting.
