Tumi (Quechua for 'knife', variants: tome, tume) is a generic term encompassing the many kinds of sharp tools utilized in pre- and post-colonial eras of the Central Andes region. Tumis were employed for a diverse set of purposes including as kitchen knives, agricultural tools, secondary weapons of warriors and hunters, sacrificial knives, barber implements, pendants, and medical tools. In addition, the tumi form, in metal, was used as a type of coin. Pre-columbian tumis were usually made of metal or stone.
