Crucible Industries’ CPM REX 121 is a high-vanadium, cobalt-bearing tool steel designed to offer the greatest wear resistance, attainable hardness, and red hardness available in a high speed steel. Created to bridge the performance gap between high-alloy tool steels and carbide materials in demanding industrial applications, when applied to knife blades, it offers extreme hardness and unequalled edge retention. This unique expression of the popular Sage 5 showcases REX 121’s remarkable properties in its full-flat-ground, satin-finished blade. To further distinguish its elite status, it also features distinctive burnt-orange-colored peel-ply-textured G-10 scales. All other features of this knife are consistent with the proven Sage 5 platform, including nested, skeletonized stainless steel liners, a high-strength Compression Lock mechanism, and a reversible wire clip that supports ambidextrous tip-up carry.
As with most Taichung examples I have, the fit and finish of this Sage5 is exceptional. The grind is very clean and came razor sharp. The design is one of the best, flickable and smooth, just the right size with perfect ergos. I have a few knives in REX121 but none this thin. Should be an excellent EDC.
