More Details

The FK One Adjust marks a new era for FK Irons. Built to adapt and engineered to perform, it delivers true FK power, precision, and comfort, designed with direct artist input to meet the demands of modern tattooing.

This is FK Irons’ first machine to feature patent-pending stroke adjustment technology, allowing you to instantly adjust your stroke length between 2.0mm and 5.0mm in 0.5mm increments without powering down. Whether you’re packing colour, creating bold lines, or working on delicate shading, the FK One Adjust adapts to every style and technique with zero compromise.

The upgraded digital touchscreen display provides full visibility over your operating parameters, letting you view your power output in either volts or hertz, whichever you prefer. Hertz mode gives a detailed insight into your machine’s performance, showing the exact frequency of needle movement per second. The ambidextrous layout ensures optimal visibility for both left- and right-handed artists.

Inside, a precision-engineered brushed motor and refined internal assembly deliver the smooth, stable performance FK is known for. The machine’s 6061 T6 aluminium body offers a balanced, ergonomic feel, while the anti-roll cap keeps it secure during sessions. Powered by dual rechargeable Panasonic batteries, the FK One Adjust provides up to 13 hours of total runtime and can be used with both short and long caps depending on your setup.
