DND · Italian Designer Handle

Boole

DND studio

Two cylinders meet and intersect with a slight shift, sharing a small portion of material. Quiet mathematical tension in solid metal. The intersection is cut from one piece of brass, not joined — the geometry is honest. Matte Black is the most common specification, where the form reads almost as a drawing on the leaf.
