Curved Door Lever

The Curved Door Lever by MATUREWARE (Futagami) is a sand-cast solid brass lever with a concave profile that follows the natural grip of the hand. Part of an architectural hardware line produced in Toyama, Japan — each piece is cast and finished by hand, resulting in subtle surface variations that deepen with age.

Available in four lever shapes (Hex, Curved, Line, Hollow) with three interchangeable back plate options (Hex, Circle, Square). Mix and match across the series for a coordinated or contrasting door set.
