From the Sanskrit word for sharpening stone, the word paragon means a model of excellence, and we aim to embody this definition in everything we do. The company name originates from my great-grandfather’s business, which began making Paragon Propellers in 1910. His firm supplied 70% of the allied forces’ propellers during WWI.
