What Benchmade says:
A new era of Adamas is here. The last thing your loadout needs is another heavy piece of gear to weigh you down, which is why the 375-1 Adamas has been re-engineered to be stronger than ever before without adding weight. Machined from CPM-CruWear tool steel, this blade brings upgraded corrosion resistance and toughness front and center. In addition to the knife itself, the sheath has been redesigned to affix with low profile MALICE CLIPS, allowing users to carry the knife on MOLLE webbing or a standard duty belt. Modify with the times, and carry with confidence.

CPM-CruWear (HRC 63-65)
An air-hardenable, non-stainless tool steel that has an exceptional balance of extreme toughness, strength, and wear resistance, making it an excellent choice for general purpose, hard-use cutting tools.

Quinn Knives' take:
When a customer walks in looking for a heavy-duty fixed blade, this is one of our first options to show them. The CruWear steel really can take a beating and the included paracord, when used to wrap the handle, gives you some extra versatility out in the field. Coupled with the ability to mount the sheath in a variety of ways, this is a knife that's mission-ready.
