Spyderco’s MT15 is the next installment in our Mule Team Project. It is made with CTS B75P powdered steel produced by Carpenter Steel of Reading, Pennsylvania U.S.A.

Carpenter’s CTS B75P is comparable in elemental composition to BG42 blade steel but is produced using a powdered steel manufacturing process rather cast steel construction. Powdered steel manufacturing renders the ingredients and carbides making up the steel’s structure, more consistent in grain size to each other and homogenize the steel. For the knife user this translates into a high-performance knife steel with exceptional wear and corrosion resistance and long term edge retention. CTS B75P’s hard vanadium carbides further augment its wear resistance and edge retention making it the new knife steel that production knife companies and custom knifemakers are excited to use.
 
The Mule Team Series is an ongoing project where the same fixed blade knife is released in different blade steel variations several times per year. Mule is the name given to a test piece in the knife manufacturing process. The project allows steel-obsessed knife knuts the opportunity to test, try and use alloys not readily available to the industry.  
 
The Carpenter MT15 CTS B75P Mule is a limited-piece run with a sharpened PlainEdge cutting edge and it’s sold without handle scales or a carry sheath, focusing the project on the steel. Leaving the knife handle unfinished opens creative possibilities for designing custom handle scales or handle wrappings and carry options. Pre-drilled holes in the handle allow for attaching scales or whatever the imagination creates.
