Description
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. Founded in 1976, Spyderco is a leading innovator in
high-performance knives, known for their signature round hole and ergonomic
designs. Trusted by outdoor enthusiasts, first responders, and professionals,
Spyderco uses advanced materials like CPM S30V and SPY27 steel to create
durable, reliable tools. With a focus on precision and innovation, Spyderco
continues to set the standard for quality in the knife industry.
