Metallblades

Metallblades is a generic term for cutting blades made from metal alloys. It covers a wide range of tools, from consumer kitchen knives and hand tools to industrial saw blades and machine-grade blades used in metalworking and woodcutting. The designation emphasizes metallic composition and engineering for sharpness and resilience rather than ceramic or composite blades.

Blades in this category have a long history, evolving from copper and bronze to iron and steel, with modern variants often using carbon steels, stainless steels, high-speed steels, and specialized tool steels. Some blades are carbide-tipped or fully carbide to improve wear resistance, and many incorporate surface coatings such as titanium nitride or DLC to reduce friction and corrosion.

Manufacturing typically involves forming the blade shape by forging or stamping, followed by heat treatment to adjust hardness and toughness, and precision grinding for a keen edge. Carbide-tipped variants use carbide tips attached to a steel shank and may be produced by brazing or cementing.

Performance depends on alloy composition, heat treatment, blade geometry, and coatings. Important considerations include hardness, toughness, edge retention, corrosion resistance, and ease of sharpening. Applications span kitchen use (sharp, corrosion-resistant blades), woodworking saws (tooth geometry and set), and metalworking blades (rigidity and wear resistance).

Safety and maintenance emphasize proper storage, regular sharpening, and avoiding dissimilar metal contact that can cause corrosion. See also blade steel, cutting tools, and wear-resistant coatings.
