In its early use in the
American Southwest, the mano and metate were used to grind wild plants. The mano began as a one-handed tool. Once the maize cultivation became more prevalent, the mano became a larger, two-handed tool that more efficiently ground food against an evolved basin or trough metate.
Besides food, Manos and metates were used to separate and pulverize

Grinding process

A Mano, a smooth hand-held stone, is used against a
metate, typically a large stone with a depression or bowl. The movement of the Mano against the metate consists of a circular, rocking or chopping grinding motion using one or both hands.
Ancient Pueblo People often set up work rooms, called mealing rooms, that were established with sets of manos and metates for mass grinding efforts.
