Spyderco Sage 5 Lightweight Orange FRN Folding Knife

The Spyderco Sage 5 Lightweight is based on CPM REX 121, one of the most exotic, high-performance powder steels available in production cutlery, a satin-finished 3-inch drop point blade fitted to a vivid orange FRN handle with a Compression Lock.

CPM REX 121 is an extreme steel originally developed for industrial cutting tools, prized for edge retention that outperforms nearly every other steel used in folding knives today, a meaningful step above even premium alloys like S30V or VG-10. That trade-off comes with added hardness that makes the steel more challenging to sharpen than a softer alloy, a fair exchange for buyers who prize edge-holding above nearly everything else. Spyderco's Compression Lock locks the blade with strength while keeping the release lever positioned safely and deliberately away from the cutting edge for added protection.

The vivid orange FRN handle keeps this lightweight folder easy to spot in a bag, on a desk, or in a truck console. REX 121 remains rare across the broader knife industry given its demanding machining requirements. Explore more Modern EDC Linerlocks.
