The ergonomic handle is designed to be held at approximately 45° from the cutting surface and keeps the hand in a radial direction from the center of the blades. Its elliptical shape and small finger grooves allow it to be comfortably held by people with small or large hands.

The depth-setting mechanism allows the blades to be fully retracted into the device for safe handling and storage, or extended to a maximum cutting depth of 1.5 cm.

Cutting depth is adjusted by loosening two knobs on both sides of the device and moving the knob up or down a slot in the housing as the blades slide along the same slot.

Markers on the housing inform the user of the blade depth in 1 mm increments. Once the desired depth is reached, the knobs are then tightened to lock the blades into place.
