Knives are tools with a cutting edge or blade, attached to a handle. They have been used by humans for thousands of years, evolving from simple sharpened stones to the sophisticated designs found today. The primary function of a knife is to cut, slice, or stab. The shape and material of the blade, as well as the design of the handle, are tailored to the intended purpose of the knife.

Blade materials vary widely, with steel being the most common due to its durability and ability to hold a sharp edge. Different types of steel offer varying degrees of hardness, corrosion resistance, and flexibility. Other materials like ceramic and obsidian have also been used for blades, each with unique properties. The edge of a knife can be straight, serrated, or a combination of both, influencing how it interacts with different materials.

Knife handles are designed for grip and control. Materials can include wood, plastic, metal, bone, or composite materials. The ergonomics of a handle are crucial for comfort and safety during use. Handles can be fixed to the blade (fixed-blade knives) or designed to fold (folding knives), offering different advantages in terms of portability and strength.

Knives serve a vast array of purposes across many different fields. Kitchen knives are designed for food preparation, with specific shapes for tasks like chopping, slicing, and paring. Hunting knives are robust tools for field dressing game. Tactical knives are built for survival and self-defense, often featuring durable construction and specialized blade designs. Craft knives, utility knives, and surgical scalpels are other examples of specialized knives designed for precise work. The study and collection of knives is known as cutlery collecting.
