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.

To turn the knife on, press and hold the button on the knife's handle. For safety, the knife turns off when you let go of the button. A contoured handle makes the knife easy to hold as you apply pressure.

Knives come with a rechargeable battery, so you can bring them anywhere you need. They also come with a pack of 40 replacement blades.

With the push of a button, these irons convert from a straight grip to a pistol grip with either a 45° or 90° head angle. Battery power and no cord means you can take them where you need them. Compared to standard cordless soldering irons, you can solder nearly three times as many joints per charge. These irons come with two tips; additional tips are sold separately.
