Blade making is the process of creating sharp-edged tools or weapons, typically from metal or other durable materials. The process often involves heating the material to a malleable state, shaping it through forging or grinding, and then hardening it through heat treatment. Common types of blades include knives, swords, and axes, each designed for specific uses. The art of blade making has a long history, with techniques varying across cultures. Traditional methods often involve hand-forging, while modern techniques may use advanced machinery and materials. Notable examples of blade making include the craftsmanship of Japanese swords and the production of kitchen knives in Germany.
