Developed in close cooperation with Crucible Industries®, CPM® SPY27® is a cobalt-enriched powder metallurgy steel that offers an excellent balance of toughness, corrosion resistance, edge retention, and ease of sharpening. Available only on Spyderco knives, this steel is the heart of the latest expression of the Manix® 2 XL. One of our largest and most formidable folders, its broad, full-flat-ground blade takes full advantage of the attributes of SPY27. The blade is supported by a high-strength Ball Bearing Lock™ mechanism and a handle featuring full, skeletonized stainless steel liners, cobalt blue peel-ply-textured G-10 scales, an oversized lanyard hole, and a reversible pocket clip that provides a choice of right or left-side tip-up carry.
