After the war, the educated class of Canzo restored its quality of life, adding infrastructure and restarting production. Despite a national battle between Catholics and Marxists, in Canzo moderate and peaceful freedom of thought was maintained, together with honest collaboration in social matters. The population grew and its density increased, so new districts and houses were built, especially in the plain of the River Ravella, in the areas known as "Parisùn" and "Gerètt". New enterprises were opened, such as the Porroni stone carving company (which created the capitals for Como's Portici Plinio), and manufacturing industries, such as iron scissors. Canzo became Italy's centre of this kind of production together with the nearby village of Premana. Every street had at least one scissor maker.
