There's two basic types of quality chef's knives: Japanese, very hard steel blades, and German high quality steel blades. Handle designs are simply a matter of individual preference. The Japanese steel is more difficult to sharpen, but once sharpened, it maintains its edge longer. These blades are usually sharpened with a razor edge, a 16-1/2° angle on either side of the edge. The German steel blades are usually sharpened with a 22-1/2° angle on either side of the edge. Both knives can be very useful in the kitchen. The German knives might be described as more rugged than the Japanese knives...not always the best for cutting sushi, for instance. The Japanese knives typically have thinner and more brittle blades. I own both and I love both. I simply use one for general kitchen work, and the other for delicate, close and precise work.
The steel blade of a knife will hold a sharp cutting edge.
An instrument with a thin bade made of steel and having a sharp edge for cutting? This is a knife. Care must be taken when handling said knife.
The Aztec sacrificial knife was typically made of flint or obsidian, which were sharp volcanic stones known for their ability to hold a sharp edge. These materials were valued for their sharpness and cutting capabilities in ceremonial rituals.
A sharp knife cuts much better than a blunt knife. A sharp knife is less likely skid off and cause an accidental wound.
By being sharpened by cutting bits of wood off of it using a knife
Knife edge: Knife edge scissors are made with the balance beam or lever arm fulcrum in the form of a hardened steel "knife edge' wedge; used to minimize friction. http://www.marthastewart.com/good-things/knife-edge-pillow
When cutting with a knife on a cutting board, materials like wood or plastic are preferable, as they tend to be gentler on the blade's edge. Wooden boards, particularly those made from hardwoods like maple or walnut, provide a forgiving surface that can help maintain sharpness. Plastic boards are also good options, especially those made from high-density polyethylene, as they are easier to clean and less prone to harboring bacteria. In contrast, glass or ceramic cutting boards can quickly dull knife blades due to their hard surfaces.
Iron or steel will hold a very sharp edge, and make an efficient wood cutting/chopping tool.
A knife is a versatile cutting tool consisting of a blade and a handle. The blade is typically made of metal and is sharp on one edge, allowing it to slice through various materials. Knives come in various shapes and sizes, designed for specific tasks such as cooking, hunting, or utility work. They are essential tools in many contexts, from kitchens to outdoor activities.
Anything that's called 'cutting-edge' is something which is at the forefront of current technology. What's cutting-edge today is unlikely to be cutting-edge soon because technological developments will have made it out of date.

Yes, a knife is typically made from hard materials, such as stainless steel or carbon steel, which provide the necessary hardness for cutting and durability. The hardness of the blade material allows it to maintain a sharp edge and resist wear during use. However, the specific hardness can vary depending on the type of steel and the heat treatment process used in its production.
