The definitive instrument for architectural drafting and precision engineering.
Constructed from a solid block of extruded aluminum, this mechanical pencil utilizes a rare "Double-Knock" retraction mechanism. The first actuation deploys the protective guide pipe, while subsequent clicks advance the 0.5mm lead. A final firm press fully retracts the entire tip assembly into the barrel, neutralizing the risk of tip-bending during transit and protecting the craftsman's pockets.
A knurled grip sector ensures absolute control, offering a low center of gravity that drives the point into the page with fatigue-free precision.
