blade

A knife is any cutting edge or blade, handheld or otherwise, with or without a handle. Knives were used at least two-and-a-half million years ago, as evidenced by the Oldowan tools. Originally made of rock, flint, and obsidian; knives have evolved in construction as technology has with blades being made from bronze, copper, iron, steel, ceramics, and titanium. Every culture has a unique version of the knife. Due to its role as mankind's first tool, certain cultures have attached spiritual and religious significance to the knife including the La Hu Si{Knives 2008}

Most modern-day knives follow either a fixed-blade or a folding construction style, with blade patterns and styles as varied as their makers and countries of origin.
