Spyderco Para-Military2 with carbon fiber handle and composite CPM-S90V/ CPM 154 steel blade, model number C81CFPE2.
Spyderco is the first production company to use this unique and very exotic, composite blade steel from Crucible Industries of New York. The manufacturing process is in itself unique. It begins with a 1-inch thick plate of CPM S90V. The plate is placed in a specially engineered and built steel can and the voided areas on either side of the plate are filled with CPM 154 powder. The can is positioned on a vibratory table to ensure consistent density in the packing of the powder and then it is welded shut and subjected to a vacuum to evaluate any oxygen. The can then enters an autoclave under extreme heat and pressure where the power forge-welds with the plate. Afterwards, the can is machined off; the remaining slab is cogged-down in a roller into flattened sheets suitable for making knife blades. Where many layered steels are produced by heating plates and then sandwiching the steels together, this process uses specialized equipment and welding techniques commonly featured in the manufacture of aircraft parts where steels are held to rigorous specializations to avoid structural failure.
The blade is ground full-flat and additional surface jimping is machined on both the spine and the forefinger choil. A line marks the juncture where two composite steels meet, giving each blade its own unique pattern that is the result of the homogeneous transition of two extraordinary modern powered metals.
Paired with a rich-feeling peel ply carbon fiber handle scales, the model offers fine-tuned ergonomics with both an oversized lanyard hole and an enlarged Spyderco opening hole. It features Spyderco patented Compression Lock that is further complemented with an ambidextrous four way clip that carries tip-up/ tip-down, left/ right-hand with the folder settled deeply in a pocket.
Made in Golden, Colorado U.S.A., the Para Military2 composite steel/carbon fiber Sprint Run is one of the rarest Spyderco knives ever produced.
