Friction Forging®: A Game-Changer

  • Friction Forged® Technology: The Apex proudly features the groundbreaking Friction Forged® Technology Steel, elevating its cutting prowess to unparalleled levels of sharpness and durability.. The Friction Forging® process results in steel grain structures 10x finer than traditional knife manufacturing methods, thereby creating a harder, thinner, tougher razor sharp edge. The DiamondBlade knives will outperform any other knife by 10 times – or better – guaranteed. Read More
  • Holds a shaving edge 10X longer: This revolutionary forging process creates a finer grain structure, leading to a blade that stays 10 times sharper, guaranteed.
  • Non-Brittle: The finer grain structure also makes the blade more resistant to chipping and breaking even at an unprecedented 65-69 Rc hardness.
  • Corrosion-Resistant: The forged zone is resistant to corrosion and rust, ensuring your knife stays reliable for years to come.
  • Easy to Sharpen: Because the blade is ground to a 9 degree (18 degree included) angle, there is less material to remove when sharpening is eventually needed.


Unmatched Quality

  • American-Made Toughness: Every DiamondBlade Knife is made in the USA with American materials, backed by a lifetime warranty.
  • CATRA-Tested Sharpness: Each blade undergoes rigorous testing on a CATRA (Cutlery Allied Trade Research Association) knife sharpness machine to ensure it meets the highest sharpness standards.
  • D2 Tool Steel: This high-quality steel forms the foundation for the patented friction forging process, resulting in an ultra-hard edge (65-69 Rc) with an 18-degree (included) sharpening angle.


Handle Material

  • G-10: Tough as nails material that is a combination of fiberglass fabric and epoxy resin. A synthetic handle that is made to be durable while providing a good non-slip grip that is easy to clean.


Lifetime Warranty

  • Free Lifetime Sharpening: We stand behind our knives! Even a DiamondBlade Knife will eventually need to be sharpened. Simply send your knife to our Texas headquarters, and we’ll professionally resharpen it for free. Learn More
  • Corrosion Resurfacing and Refurbishment: If a complete refurbishment service is needed, our technicians will refurbish your knife to keep it looking and performing like new.
  • If you experience an issue with your knife, simply contact us, and ship to our Texas Headquarters and we will completely repair, or replace your knife. Learn More



  • Maintain the Edge: A few strokes on a ceramic rod on either side will keep your DiamondBlade razor-sharp.
  • Cleaning: Wash with soap and water after use, then follow up with WD-40 or another solvent to clean the blade’s micro grain structure. Wipe dry to prevent rust. This product is not dishwasher safe.



  • Secure and Convenient: Each Apex Knife comes with a sleek American made leather sheath.

  1. Mark S. Reglewski

    I have been searching for a pocket knife that is legal in Chicago for years. (It must have a blade no longer than 2.5 inches.) Finding such knives that don’t have a toothpick-narrow blade has been difficult. The ones I have found had blades of inferior steel that did not hold an edge well. This little Apex knife is what I have been looking for. Shaving sharp out of the box. For common tasks like cutting down boxes for the trash, slitting open envelopes, opening packages, cutting rope and string it is a little beast. None of the inferior knives I have settled for in recent years would still be sharp. Even after slicing through rope and cardboard quite a few times, the blade will dry-shave hairs off my arm.

    My search for a good knife with a short blade is over.
