It is a component which in earlier years they were using it for mixing flour+water and make traditional baking bread.
If any of you have ever seen one but not in CYPRUS or GREECE let me know the country.

When the SKAFI was cracked people used to nail some aluminium in order to slow down and prevent any further crack.
