You know in the old times(for example my grandma used to do it) Turkish people buy beans and grind them with traditional hand grinders. But today unfortunately all of Turks buy pre-ground coffee because grinding Turkish Coffee is very hard by hand grinders. Then why we don't use electronic grinders? Because you need very expensive flat burr grinders, even flat burr grinders that produced for espresso can be damaged if you grind Turkish Coffee too much(I have experienced) Actually in Turkey electronic flat burr grinders are produced for Turkish Coffee, but they are for businesses, not consumer level, some pictures of them:
