The Spyderco Sage 5 folding knife (brand part no. C123GBORP) showcases Crucible Industries’ CPM REX 121, a high-vanadium, cobalt-bearing tool steel developed to deliver the greatest wear resistance and attainable hardness available in a high-speed steel. Its full-flat-ground, satin-finished blade takes full advantage of REX 121’s properties, paired with distinctive burnt-orange peel-ply-textured G-10 scales that set this Sage 5 apart.
