Folding knife KeyOne (flipper) – a new, incredibly beautiful and stylish work from our workshop. Currently, the model is represented by three prototypes: versions of Art-Titanium, Mirror, and Stonewash. In the first version (Art-Titanium), the author’s knife is equipped with a blade polished to a mirror Shine and a handle made of titanium and carbon (titanium is covered with the author’s art-anodizing, own development, carbon – author’s).
