The GEO Knife Cirex by designer Fabian Hobbelen combines premium materials, practical ergonomics, and ultralight construction in a capable folding knife built for everyday carry. Designed for the outdoors, campsite, workbench, and daily utility, the Cirex delivers a secure, comfortable grip while keeping overall weight remarkably low. This version pairs a rugged stonewashed M390 blade with a green G10 handle, creating a dependable EDC with a clean, outdoors-ready appearance.
The 3.5-inch clip point blade is crafted from Bohler M390 stainless steel, a high-performance powder metallurgy steel known for excellent edge retention, wear resistance, and corrosion resistance. Vacuum and cryogenic heat treatment brings the blade to HRC 60-62 hardness, helping it maintain a reliable working edge through repeated use. The flat grind provides a practical balance of slicing performance and blade strength, while the stonewashed finish gives the blade a rugged appearance that complements the knife's working character. The clip point profile provides a useful combination of a precise tip and capable cutting edge, making it well suited for everyday utility, campsite chores, and general cutting tasks.
The 4.5-inch handle is constructed from durable G10 and finished in green. Lightweight, strong, and well suited for outdoor environments, G10 helps keep the Cirex easy to carry without compromising its secure feel in hand. At 0.48 inch thick, the handle offers substantial structure while maintaining a streamlined profile. Its ergonomic shape promotes confident control through a variety of cutting positions, whether you're opening packages, handling routine utility work, or spending time outdoors.
A crossbar lock provides secure blade retention and smooth operation, while the ambidextrous design makes the Cirex convenient for both right- and left-handed users. Bronze washers support smooth blade movement, and the 6AL4V titanium clip, pivot cap, titanium pivot collar, and screws add lightweight strength and premium detailing. The right-hand tip-up pocket clip provides a secure and accessible carry position.
Measuring 8.0 inches overall with a 3.5-inch blade, the Cirex offers impressive cutting capability while weighing just 2.95 ounces. That ultralight construction makes it an excellent choice for anyone who wants a full-size folder without unnecessary pocket weight. The combination of M390 steel, G10 construction, and titanium hardware gives the Cirex a strong foundation for daily use.
Designed by Fabian Hobbelen and manufactured in China, the GEO Knife Cirex balances premium performance with practical, lightweight construction. With an ETA around July, it's ready to become a reliable part of an EDC rotation, whether you're headed to work, the campsite, or the trail.
