Wästikivi oy
In 1998, Sari and Ilkka Tuomaala founded Wästikivi AG. Wästikivi extracts, processes and sells the well-known phyllite sharpening stone that originates from Längelmäki. The history of the Längelmäki grindstones goes back to the 17th century. Wästikivi's concern is to preserve and continue the tradition.
