By value

Introduced era places a tool in the period when it first came into use. Wikipedia states, "Early human tools, made of such materials as stone, bone, and wood, were used for the preparation of food, hunting, the manufacture of weapons, and the working of materials," long before metal or powered tools existed. Browsing by era shows how the tools used in home crafts have developed over a very long span of time.
