Carrying a knife was an essential part of one's activities during 99.9% of human history.

Scientists have found traces of blood, muscle, skin and hair on stone knives used by the Maya. They were used to cut scorpions and snakes, to render them powerless. In Ancient Egypt, flint blades were used for mummification, but were considered to be magical objects. The Inuits have the ulu knife, which they use for food processing, hair cutting, skinning and cleaning animals, fighting, or to build igloos. Knives were essential for survival in most cultures, since they were necessary for harvesting crops and raising livestock. New materials are being developed and introduced into the knife industry.
Stainless steel is still the top material for knives, aluminium is also popular, but is less durable. Wood is a popular handle material, but metal handles are also used. The history of the knife handle is divided between wood handles and 'other materials'. In the Stone Age, knives had a distinct blade and handle, but made out of one solid piece of quartz, flint, or obsidian. Blades and knives have evolved over the last 600 years, but the concept is still the same. The iron alloy steel, made from wood ash is still the most widely used material for knives and other sharp weapons. The Iron Age started about 3500 years ago and used iron to make stronger and more durable tools. Sharpening stones were used to keep metal blades as sharp as stone blades. The mining of minerals opened up new trade routes and increased communication between groups and cultures.
After the appearance of Homo sapiens, sharp stone tools became more advanced in design, and metal tools became more durable.
These tools allowed our hominid ancestors to hunt, fish, defend themselves against animals, harvest and process food. Archaeologists have discovered sharp-edged tools as ancient as 2.6 million years old. The invention of knives not only made life easier for our ancestors, but gave them more spare time, during which they could socialize or develop new skills. The invention of the cutting edge, such as knives, has allowed us to reach the top of the food chain in a relatively short amount of time.
