I can tell you that the concept of knives has existed for thousands of years, and various types of knives have been used by humans throughout history for hunting, cooking, self-defense, and various other purposes.
In a historical context, the first knives were likely made from stone, bone, or other natural materials, shaped and sharpened for cutting and carving. Over time, humans developed metallurgy skills, leading to the creation of metal knives, which became more durable and versatile.
