Steampunk Meets EDC Pen

Gennai Pen SL01 is a compact mechanical ballpoint pen that turns everyday writing into a steampunk-inspired ritual. Designed by Japanese knife artist Hidetoshi Nakayama and developed by TACTICALGEEK, it combines exposed screws, layered construction, and a Telegraph Key style lever for a clear, satisfying click. Press the top button to extend the refill, then press the side Telegraph Key to retract, creating an addictive mechanical cycle you can fidget with anytime. A mechanical pocket clip grips your pocket or organizer with the same engineered feel, while the stainless steel body, CNC machining, and SCHMIDT P900M and G2 refill compatibility keep it ready for daily carry, use, and collecting. Back Gennai Pen SL01 on Kickstarter now.
