When selecting craft tools, the material composition directly impacts longevity and precision. For cutting tools like rotary cutters or precision knives, prioritize SK5 high-carbon steel or tungsten carbide blades for superior edge retention. For hand tools like pliers or hammers, look for drop-forged chrome vanadium steel with a rust-resistant coating. Ensure handles feature ergonomic TPR (Thermoplastic Rubber) grips to reduce user fatigue during prolonged use, which is a critical factor for B2B buyers supplying professional workshops.
