The mark brand " Opinel " was collectively deposited by Pierre Opinel, his brother Daniel and the son of this last one, Joseph Opinel in 1904.
Afterward each left from his part; Joseph Opinel continued the business of his father and registered trademark of the "main couronnée" in 1908, Pierre registered trademark " croix & palme " in 1914 and the third branch stemming from Jean, brother of Joseph, registered trademark " La Croix de Savoie " in 1927 before being acquired by joseph's branch which only continues today. The "Coutellerie savoisienne" based by Pierre Opinel in the brand "Croix & Palme" stopped its activity in 1967. Pradat-Brun made razors for this company.
I think that your razor was also made by a subcontractor because "Opinel" (brand "main couronnée") is as you know, specialized in the Pocketknife but I don't know the name of this company.
