After the initial sketches Styletto/Katana 4, these are almost final CAD files used for fabrication. Laquer + leather + steel. Katana share same DNA. “It starts with a dream, a few hundreds sketches, 5 or 10 proof of concept prototypes and… CAD drawings. From the sketches it’s easy to see the visual links between earlier Katanas. Expect swoopy curves and prestance. More to come.”
