Fjord leather shell edge wear at the curved leading edge
The Fjord (Patricia Urquiola, 2002) shell concentrates daily contact at the curved front edge. Aniline leather with no protective topcoat thins and splits at year eight to twelve. Most failures arrive as a split running the full arc of the leading edge. Owners sometimes apply commercial leather cream, which does nothing on raw aniline and can stain adjacent fabric. See cracking repair for split-edge technique. Compare aniline vs semi-aniline leather.
