Mule Team™ CTS® B70P

This model is no longer in production. 

Spyderco’s Mule Team™ Series is an ongoing project that enables steel-obsessed knife enthusiasts to test different blade materials using the same exact fixed-blade design platform. Sold without handles or sheaths, Mule Team blades are also ideal for aspiring knifemakers and hobbyists.

This expression of the Mule Team concept features Carpenter® CTS B70P® blade steel—a high-chromium, air-hardening steel alloyed with molybdenum, vanadium and niobium. Like conventional steels, the particle metallurgy process begins with a homogenous molten bath of high-alloy steel. However, rather than being poured into ingot molds, the molten steel is forced through a nozzle under high pressure to create a spray of small spherical droplets that quickly solidify into powder particles. The small size of the particles forms micro-ingots, drastically reducing the alloy segregation in the steel and ensuring an extremely fine, uniform carbide structure. This enhances the steel’s edge retention, as well as its grinding and polishing characteristics.

CTS B70P is a powder metallurgy derivative of Carpenter’s CRB-7 alloy, but offers improved wear resistance and hardness capability. Its corrosion resistance is very comparable to 440C stainless steel. Collectively, these qualities make it an excellent candidate for cutlery applications.

All Mule Team blades are sold consumer-direct and available only at the Spyderco Factory Outlet or through Spyderco.com.
