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, we decided it was time to create our own. In close cooperation with Crucible® Industries, we have 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. This supercharged version of the popular Para 3 Lightweight enhances all the proven features of the standard version with its high-performance CPM SPY27 blade.
