DENISON, Tx — DIAMONDBLADE, LLC, knife manufacturing company has focused on combining American craftsmanship with state of the art engineering and research to build technologically advanced knives. The United States Patent and Trademark Office has issued US Patent 8,186,561 covering Friction Forging® (solid state processing) of hand-held knives to Founder / Managing Partner, Charles Allen.  DIAMONDBLADE, LLC. has exclusive rights to the patented technology resulting in unsurpassed knife performance.
“Friction” Forging® is a localized forging process achieving high, transformation temperatures and high loads against a blade and then employing specialized techniques to achieve a rapid quench. Friction Forging® is performed on the blade in the area that becomes the edge. Friction Forging® uses a specially designed tool made from Polycrystalline Cubic Boron Nitride (PCBN), a material second only to diamond in hardness. During forging, the PCBN tool penetrates the blade while rotating, which creates frictional heating. When the tool is fully engaged, it moves along the eventual blade edge under high forging pressures, creating dynamic microstructure shearing that produce nanosize blade microstructures.  
DiamondBlade knives have been awarded “1st Place” for three years in Field & Streams “Best of the Best” knife competition category.
"DiamondBlade knives will take and keep an edge like nothing else on the market."
