The FK Irons ONE Adjust is the wireless tattoo machine built for artists who refuse to compromise. Whether you're laying crisp lines, packing vibrant colour, or blending seamless gradients, this machine adapts to your technique — not the other way around. With a single quick-turn dial, you can shift stroke length on the fly, giving you full control over needle depth, speed, and feel without ever breaking your creative flow.
Imagine finishing a bold traditional piece, then dialling back for a delicate fine-line portrait — all with the same machine, in the same session. That's the freedom the ONE Adjust delivers.
The ONE Adjust is engineered to perform across every major tattoo discipline: fine line, realism, black & grey, traditional, neo-traditional, colour saturation, and soft shading. One machine. Every style.
FK Irons has been at the forefront of tattoo machine innovation for over a decade. Trusted by world-class artists across North America and beyond, every FK Irons machine is engineered with obsessive attention to detail — because your tools should be as precise as your art.
