Benchmade Adamas

The Benchmade Adamas takes its name from Greek and Latin roots meaning ‘unconquerable’ or ‘invincible’, a fitting description for one of the toughest production folders ever made. Designed by custom knifemaker Shane Sibert with direct input from military personnel, the Adamas was created specifically for Benchmade's Black Class tactical line. It was first released in 2011 with D2 tool steel, then, ten years later, Benchmade refreshed the entire Adamas family with upgraded materials and refined geometry, making these already formidable knives even better.

What sets the Adamas apart is its unapologetic overbuilt construction. The original model embodied the term ‘tank-like’ with muscular proportions and beefy dimensions. The current generation maintains that toughness but sheds unnecessary weight through careful redesign. The 9.7cm drop point blade now uses CPM CruWear steel heat-treated to 63 65 HRC, significantly harder than most production folders. This provides exceptional edge retention and wear resistance. At 3.6mm thick, the blade remains substantial without being unwieldy. Non-reflective Cerakote coating in black or Flat Dark Earth protects the steel.

Available configurations include the full-size 275 folder weighing 183g, the Mini Adamas 273 for more compact carry, and the fixed blade 375 with skeletonised handle. The folder features machined G10 scales over full stainless steel liners rather than titanium, contributing to the ‘Heavy Metal’ feel. Deep carry pocket clip ensures secure retention.
