A blade is part of a tool, weapon, or machine whose edges are designed to pierce, cut, or scratch material surfaces. Blades can be made of materials such as flint, metal (usually steel), ceramics or other materials. Blade is one of the oldest human tools, and has been used in combat, food preparation and other purposes.

The manufacturing of mechanical parts has special requirements for cutting tools. The coating solutions provided by HCVAC fully meet the cutting requirements of the mechanical engineering industry, thus providing a decisive performance advantage. Blade coating reduces friction, wear and corrosion. Coated tools can process demanding materials faster, reduce material consumption and improve quality.
