About CPM-SPY27 Spyderco has long been an industry leader in the use of exotic, high-performance blade steels. After years of using the best materials the world’s leading steel manufacturers could provide, they decided it was time to create their own. In close cooperation with Crucible Industries, they've developed CPM-SPY27 - a particle metallurgy stainless steel containing a proprietary mix of alloys, including vanadium, molybdenum, niobium, nitrogen, and cobalt. This remarkable composition, enhanced by the amplifying effects of cobalt and the state-of-the-art Crucible Particle Metallurgy process is produced exclusively for Spyderco and will be featured in select USA-made models. Every knife made with this steel will also have a distinctive cobalt-blue handle color that highlights its elite pedigree.
