Benchmade® Adamas® Family

No matter the mission, specific unit SOP requirements, or knife-type preferences, the Benchmade® has you covered.  The Adamas® family is a performance-driven military grade knife.


Shane Sibert designed the Adamas® 375 fixed blade combat knife. The black or FDE finished D2 steel drop point blade has a plain cutting edge and serrations on the spine. The handle is skeletonized with optimally positioned grooves. The Adamas® fixed blade knife also comes with a black injection-molded sheath with secondary locking strap and tension screw for secure storage and custom-tuned deployment.  You can also use 550 paracord to customize the grip or use for added texture and grip circumference.
