FK One Adjust Machine

The FK One Adjust takes the tattoo industry to the next level with patented stroke adjustment technology and a completely reimagined design, designed with artists in mind.
Change stroke on the fly in seconds—from 2.0mm to 5.0mm in 0.5mm increments. This adaptability is built directly into the frame, providing unlimited versatility. The FK One Adjust eliminates the need to operate multiple machines or eccentrics. Go from heavy styling to fine detailing in a single, seamless workflow with precision you can feel.
This machine boasts true innovation that delivers results: the evolution of engineering is at the heart of what makes the FK One Adjust so remarkable. The stroke adjustment system operates with mechanical precision, allowing you to fine-tune response mid-session without having to turn off—something no other stroke adjustment system can do. Designed with the needs of craftsmen at every stage of their development in mind, this clipper is a powerful tool designed with craftsmen in mind. Every mechanical decision was made to ensure consistent torque, clean movement, and reliable performance in any style.
The advanced digital display provides complete control. Display output in volts or hertz—your choice. Hertz accurately displays the number of needle movements per second, providing the most accurate performance information. It's designed for complete visibility and control.
