The collection comprises a lever handle, key escutcheon and thumb turn, as well as a door knocker, pull handle, flush pull and door stop. Like the rest of the d line portfolio, each piece is minimalist enough to be timeless in its design, its beauty coming from its rounded profile and inflated silhouette, rather than from superfluous details. The pieces are enduringly crafted in the highly resilient AISI 316 stainless steel preferred by d line and enhanced by a tight edit of finishes for different expressions in colour.

Tom Dixon describes door handles as having “a particularly difficult and hyper-functional set of challenges, because they’ve evolved rather than being designed.” He observes that often designer handles are less functional than traditional ones, because a handle is something with which there’s little to be done to affect the aesthetic beyond what's come before. The challenge for him and his studio, therefore, has been the creation of something that functions well, yet looks distinctively different from what’s already out there.
