For those seeking unparalleled edge retention in an ultra-lightweight format, look no further than this elite rendition of the Sage 5 Lightweight. Its full-flat-ground, satin-finished blade is crafted from state-of-the-art CPM REX 121 tool steel. Renowned for its extreme hardness and edge-holding properties, this remarkable steel features more than three percent carbon and high volumes of tungsten, molybdenum, vanadium, and cobalt. All other features of this knife are faithful to the standard Sage 5 Lightweight platform, including a stout Compression Lock mechanism, nested, skeletonized stainless steel liners, a reversible deep-pocket wire clip, and a lightweight, injection-molded fiberglass-reinforced-nylon (FRN) handle. To further highlight its advanced blade material, the FRN handle of this knife is molded in a distinctive burnt-orange color.
Zero complaints on this one. Pretty perfect right out of the box - drop-shut action, zero blade play, excellent sharpened edge (shaving sharp and even), and they added a nice small ground chamfer to the back edges of the blade. This is the fourth Sage5 I've owned and the best yet. Time will tell how good the Rex121 is, but this is a superb build.
