The birchbark horns in the coat of arms are reminiscent of the times when they were used for signaling in a settlement that spread over large forest areas. They were also used to scare forest predators away from cattle while they were grazing in forest pastures. The golden trefoil crosses refers to the parts of three old church parishes that formed the Pielavesi parish. The coat of arms was designed by Ahti Hammar and Niilo Toikkanen, and was approved by the Pielavesi Municipal Council on July 26 and December 15, 1953.
