Reimagine daily versatility with a machine built to do it all. Building on the core strengths of the original, the FK One Update is a true all-rounder designed for artists who want one reliable machine across lining, shading, and packing. It’s built to stay consistent in the hand and steady in performance, so you can move through a full session without switching tools. 

Power through longer sessions with upgraded dual-battery performance. Dual rechargeable battery options (18500A & 18650A) provide flexibility and extended runtime, delivering up to 5.5–6.5 hours per battery depending on setup. A 1.1” digital LCD display is integrated into the housing, giving you a clear, real-time view of voltage and system settings while you work. 

Reduce fatigue with a lightweight, balanced build. At 215g (233g with battery), the FK One Update is designed for control without unnecessary weight. Its balanced form pairs directly with Ergo Shield grips for fast setup and improved comfort, helping reduce hand fatigue through longer sessions. 

Dial in your work with precise stroke and voltage control. Available in 3.0mm and 4.0mm fixed stroke options, the FK One Update is tuned for dependable performance across core techniques. Voltage adjusts in 0.2V increments for fine control, with a 5–12V operating range that gives you flexibility across different styles and skin types.
