This A4 poster features an industrial design technical drawing (also known as a product design line drawing) of the Blanchard L’Indispensable Knife, a timeless and functional tool, the L’Indispensable is both a working knife and a beautiful object in its own right. Made to the same design for over a century.
 
The illustration highlights the form and function of this classic tool, reflecting the craftsmanship and long-standing heritage of Vergez Blanchard, the French toolmaker known for precision, durability and traditional manufacturing methods.
 
The restrained, technical style makes it well suited to workshops, studios and creative workspaces, where it serves both as decoration and as a quiet reference to the craft of leatherworking.
