Spyderco’s Mule Team™ project offers knife enthusiasts and aspiring makers a rare chance to explore the performance of different steels using a consistent fixed-blade format. The latest in the series, MT45, features Z-12Ultra BQ™, a high-performance cutlery steel from Zapp Tooling Alloys, designed for extreme wear resistance and toughness in knife applications.

This unique steel, adapted from industrial tooling uses, makes the MT45 a standout for steel testing or custom builds. Available in both PlainEdge™ and SpyderEdge™ configurations, each Mule Team blade is sold bare (no scales or sheath) and in limited quantities—perfect for serious steel nerds and DIY knifemakers alike.
