SP123GBORP: C123GBORP Sage 5 - Burnt Orange CPM-REX 121
Spyderco
Crucible Industries' CPM-REX 121 is a high-vanadium, cobalt-bearing tool steel crafted to provide exceptional wear resistance, unmatched hardness, and enduring sharpness. Bridging the gap between high-alloy tool steels and carbide materials in industrial settings, it delivers unparalleled performance. In this distinctive Sage 5 variant, REX 121's exceptional properties shine through its full-flat-ground, satin-finished blade. Setting it apart, burnt-orange peel-ply-textured G10 scales enhance its elite status. Other features remain true to the Sage 5 design, including nested, skeletonized stainless steel liners, a robust Compression Lock mechanism, and a reversible wire clip for versatile, ambidextrous carry.

Rex-121
The edge lasted longer than my sage 1 in Maxamet. I cut thick heavy duty cardboard, twine off hay bails, plastic banding and many other things that are hard on edges. I can say i would make the purchase again. It does take some time to sharpen when you do dull it but it is doable with diamond sharpeners. It is a touch chippy compared to some other knives I have but the REX-121 and maxament have been the only 2 I have had that I’ve actually been impressed with how well they hold an edge.
